Overview

Unimesh 2 - Editing and UV Mapping
Base Game
Author	HystericalParoxysm

What this tutorial will teach you

This tutorial builds on the techniques learned in the Unimesh 1 - New Mesh Basics tutorial. Once you have learned the skills taught in that tutorial (creating a new mesh, doing a simple edit on it in Milkshape, and getting it to show up properly in Body Shop/in-game), you can begin doing more complex edits as explained in this tutorial.

Here, we will be doing a simple edit to a dress: making the hem longer, and flaring the bottom of the skirt. We will also be learning how to adjust the uv/texture mapping so that the textures are not distorted on our edited mesh. We will also learn how to do the same edit to the fat morph at the same time when doing simple edits.

Warning!

Meshing is difficult! Meshing is hard! Meshing is time consuming and frustrating! This is not an easy process. Though everything will be fully explained, it's possible that you may miss something or it won't work the first time. If that happens, start over from the beginning after taking a break and try again. There is no easy 5 minute meshing technique that we're not telling you - this really is the easiest, best way to do it.

If you get completely stuck, scroll to the bottom - there's a "Having trouble?" section which goes over common mistakes and errors you might get in doing this tutorial, and how to fix them.

Prerequisites

You MUST have prior knowledge of creating clothing using Body Shop. This is not for absolute beginners at Body Shop - experience in creating clothing recolours/retextures will serve you well going forward. We will not be going over how to make new textures or change colours on your new mesh - you should already know all that stuff! If you do not have that preexisting knowledge, do not continue with this tutorial. Instead...

See: Body Shop Recolouring Tutorials

You MUST also have gone through the first Unimesh tutorial! This tutorial builds on the techniques learned in the first tutorial. This tutorial will -not- teach you the basics of making a new mesh as that is taught in the first tutorial - I will be mostly skipping over those parts as you should already know how to do them. If you have not already completed the first Unimesh tutorial, you -must- do that tutorial before attempting this one or you will be completely and utterly lost.

See: Unimesh 1 - New Mesh Basics

Special Thanks

This tutorial is a revised version of Tiggerypum's Unimesh 2 tutorial. It utilizes updated tools to make the editing easier, but still does the same project and builds on what she wrote originally. Many thanks to Tig for her original tutorial, and everything she's taught me about meshing.

What you will need:

You must download and install all of the following programs and utilities before beginning this tutorial. If you are having any trouble or questions on installing them, please look for info on their individual sites/pages.

You SHOULD already have most of these from the first tutorial (except Vertex/Normal Data Merge), but in case you've uninstalled them or whatever since, here's the links again:

• Milkshape - Current version as of this writing is 1.8.3. We will be doing our mesh editing in Milkshape. This is not a free program! It will allow you to use it free for 1 month, but after that you will need to pay $25 to register it. It is worth the money. There is no version of this tutorial using free programs - nothing else uses Unimesh and allows you to make major edits for such a low price.

• Unimesh Plugin for Milkshape - Current version as of this writing is 4.09. This plugin allows proper import/export of Sims 2 meshes into Milkshape. Unimesh is free. Read the included "UniMeshReadMe.txt" file for installation instructions.

• SimPE - Current version as of this writing is 0.68. Get whatever the latest version is. SimPE allows creation of a new mesh package linking the mesh to a recolour file.

• Needed Software to Run SimPE - This is listed as a heading on the SimPE download page with links there. You will need both the Microsoft .NET Framework Version 2.0 (this is different from .NET 1.0!) and Managed DirectX 9c (this is different from regular DirectX!) - make sure to download and install both or you will get errors on the SimPE parts.

• Vertex Data Merge/Normal Data Merge Plugins for Milkshape - A great little plugin by Wes_H which will make the edit we're doing much, much easier. You should also follow Wes's instructions on how to set up the plugins as shortcuts in Milkshape before continuing as it will be much easier to use them as keyboard shortcuts than through the menu.

• 1-2 Hours to complete this tutorial, assuming you do it right the first time. It may be quicker or slower depending on how fast you read and work.

The Tutorial:

You may click on any image below for a larger version. Images are shown thumbnailed here for faster page loading, but all images will display full-size if clicked.

Part 1 - Create a Recolour

As in the first tutorial, we will need to start by creating a recolour in Body Shop of the base mesh we want to edit. We will then use this recolour to find its associated mesh, and will link to it for our modified mesh in subsequent steps.

As with the first tutorial, please follow along using the same mesh that is shown here - it will make it much easier for you to complete this tutorial. Do not attempt to use a custom mesh - please use the original Maxis mesh which is being used here.

1. Run Body Shop, and Make a New Project: Open Body Shop, and once it's open, click Create Parts - Create Clothing - Everyday. Then make sure to select the teen female age group - we're going to be editing a teen female dress this time. Scroll toward the end of the catalog until you find the dress pictured. It comes in several clothing options, but I'm choosing the blue one with babies, mainly because I find it confusing and creepy, but also because it will be good to show whether our texture is distorted in subsequent steps. Click on the button at the bottom to Export Selected Textures.

2. Name Your Project: Let's call this project "TutorialDressTwo".

3. Tooltip and Import: Type a tooltip for your project. "TutorialDressTwo" is a good tooltip. You can leave it as everyday clothing. Then click the button at the bottom to Import to Game.

4. Close Body Shop.

Okay, now we have our recolour ready...

Part 2 - Create a Folder

Again, as we did in the first tutorial, we're going to be editing, importing, and exporting a lot of different files, and we need to keep them organized. So as you did in the first tutorial, make a new folder on your computer's Desktop, or whereever you can easily find it. Don't use the same folder as the first tutorial - create a new, empty folder so we can keep all our parts straight.

Call your new folder "TutorialDressTwo Files".

Part 3 - Assemble a Mesh Package

Now it's time to put together our mesh package, using the mesh used by the recolour we just made. This should be familiar from the first tutorial, but here's a quick overview.

1. Run SimPE.

2. Create a New File: File - New to create a new, empty file.

3. Run PJSE Mesh Tool: Tools - PJSE - Body Mesh Tool - Extracting Stage

4. Browse for Your Recolour: In the popup you get, click on the Browse button. In the next popup, browse to your My Documents\EA Games\The Sims 2\SavedSims\ and find your recolour file - it should be named something like "5f9567f5_TutorialDressTwo.package" - Select it and click Open. PJSE Body Mesh Tool will find the four parts for your mesh and put them in your new file. You will see a GMDC, GMND, SHPE, and CRES once it's finished.

5. Fix Integrity: Make this mesh file a new, unique mesh by giving it a name in Fix Integrity. Tools - Object Tools - Fix Integrity. In the box at the top, type a name for your project. Call it "TutorialDressTwo_YourNameHere" and then click Update. The entries should all change names. Then click OK. You now have a new, unique mesh file.

6. Save Your Mesh: File - Save As and save your mesh file into your "TutorialDressTwo Files" folder you made in Part 2. Call your file "TutorialDressTwo_MeshFile.package" so you know exactly what it is.

Part 4 - Link the Mesh to the Recolour

And as in the first tutorial, we now need to link our new, unique mesh made in Part 3 to the recolour file we made in Part 1.

1. Open the Recolour File: In SimPE, open the recolour file you made in Part 1. Remember, it should be in My Documents\EA Games\The Sims 2\SavedSims\ and called something like "5f9567f5_TutorialDressTwo.package".

2. Look at the 3DIR: Select the 3DIR (3d ID Referencing File) in the Resource List. This is the resource which contains the information that links your recolour file to your mesh.

3. Use PJSE Body Mesh Tool - Linking Stage: With the 3DIR still selected, click on Tools - PJSE - Body Mesh Tool - Linking Stage. Click OK to the warning message popup you get. In the Open dialog, titled "Select Custom Mesh Package" browse to your "TutorialDressTwo Files" folder you made in Part 2. Select your mesh file that you made in Part 3., which is called "TutorialDressTwo_MeshFile.package" and click Open. You'll get a popup telling you to not to commit, but to select any other resource. Click OK, and click on any other resource besides the 3DIR in the Resource List.

4: Save: File - Save to save changes to your recolour file. Your recolour file should now be linked to your new, custom mesh.

5: Copy Mesh File to Downloads: Copy your "TutorialDressTwo_MeshFile.package" file from your "TutorialDressTwo Files" folder to your My Documents\EA Games\The Sims 2\Downloads folder.

6: Check in Body Shop: Run Body Shop, go to Create Parts - Start New Project - Create Clothing - Everyday - Teen Female. Your recolour should be the first thing showing up, with your "TutorialDressTwo" tooltip. When you select it, it should look like the same dress it was before. That means your linking has worked properly. Close Body Shop.

Part 5 - Extract the 3D Model

The last step before editing is to extract the GMDC (mesh file) so we can import it into Milkshape.

1. Open Your Mesh File in SimPE: Open SimPE if it's not already still open and browse to your "TutorialDressTwo Files" folder. Select your "TutorialDressTwo_MeshFile.package" file and open it.

2. Extract the GMDC: In the Resource List, right-click on the GMDC resource and choose Extract.

3. Save the GMDC: Save the GMDC to your "TutorialDressTwo Files" folder. Call it "Extracted_GMDC" - then close SimPE.

Part 6 - Edit the Mesh in Milkshape

Yay, we're finally to the actual editing part! As mentioned at the beginning, we're just going to do the most basic, simple of edits, but it will be enough that you can see that your mesh has changed when you view it in Body Shop.

1. Run Milkshape: You should have a Milkshape shortcut on your Desktop from when you installed it. It can also be run through Start - All Programs - Milkshape 3D 1.8.3 - Milkshape 3D 1.8.3. If you get a warning saying your copy is not registered and expires in some number of days, just click OK.

2. Hide Keyframer: Before we start editing, let's change a couple settings in Milkshape first. Under the Window menu, click on the "Show Keyframer" option to uncheck it. This will hide the keyframer at the very bottom of the Milkshape window. The keyframer is used in making multi-frame animations. Since we don't need it, we're hiding it.

3. Uncheck Smooth All: Click on the Groups tab over on the right control panel. Then look at the bottom of the controls there. There is an "Auto Smooth" option which is checked by default. Uncheck the Auto Smooth box. This is a very important option - if it's left checked, you will ruin your mesh as soon as you import it so make sure it is unchecked so the box is blank.

4. Uncheck Show Skeleton: Click on the Joints tab over on the right control panel. Look in the middle of the options, right under "Vertex Weights" for the "Show Skeleton" option. This will be checked by default. Uncheck the Show Skeleton box. We will not be editing or using the skeleton, so it's not necessary that it be shown for this tutorial. If you see a bunch of crazy blue lines and circles after you've imported, you forgot to uncheck this option.

5. Use Unimesh Import: Click on File - Import - Sims 2 UniMesh Import v4.09. There are a couple Unimesh options in Import so make sure you choose the right one - you don't want the ObjX Data Split Import.

6. Import Extracted GMDC: You'll get an Open dialog box titled "Sims 2 UniMesh Import V4.09." Browse to your "TutorialDress Files" folder. There should just be one selectable file there - "Extracted_GMDC.simpe" - this is the 3D model you extracted in Part 5. Select that file and click Open.

You will get a popup asking you a question - "Create blend groups?" Click Yes as you do want to create blend groups - this will import any morphs such as fat or pregnant. You always want to make sure to at least have a fat morph for your meshes!

You will probably also get a popup saying "Some Skin Weights do not equal 100%. Do you want these corrected?" Click Yes - this will fix any incorrect bone assignments that are under 100% - don't worry about what that means now. It will be covered in later tutorials. Just remember that you do want to say Yes to this question.

7. Basic Milkshape Movement Controls: You should now have a 3D model imported into Milkshape! Let's take a moment to review the Milkshape controls so you can get a closer look at what you have imported.

• CTRL-click and drag to move up, down, left, and right.
• SHIFT-click and drag to zoom in and out.
• Click and drag to change the angle of the camera in the bottom right (3D view pane).
• If you get lost and lose your model, don't panic! Right-click in the pane and choose Frame All.

Take a moment to try the different controls and see how they work to view the 3D model in both the wireframe and 3D views. When you're done, right-click in each pane and choose "Frame All" to get it back to how it was originally.

8. Hide Fat and Pregnant Morphs: This mesh we're editing has both fat and pregnant morphs. That's great, but we don't want to change those just yet. So click on the Groups tab. Click on the second item in the list, "~00MORPHMOD.1" which is the fat morph. Then click the Hide button down below. Now click on the last item in the list, "~00MORPHMOD.2" which is the pregnant morph. Then click on the Hide button again. This hides both of your morphs, leaving only the normal body (the "body" group) showing.

9. Show Wireframe Overlay: In the 3D view pane (bottom right), right-click anywhere. On the menu that pops up, make sure the "Show Wireframe Overlay" option is checked. This will put a wireframe view on top of our 3D model and will make it easier to see what we've selected in the next few steps.

10. Select Back Part: Now we're going to select the back part of the dress and zoom in to view it more closely. To do that, click on the Model tab. Then under Tools, click Select. Under Select Options, make sure Vertex is selected. On the checkboxes underneath, make sure "Ignore Backfaces" is not checked. Now, in the top right pane, drag a box around the upper part of the back of the dress, making sure to select all of the dangly thing. This doesn't have to be exact - just select some of the upper back.

11. Frame Selection: Right-click in the upper right pane where you just selected the back and choose "Frame Selection" to zoom in on the area you selected.

12. Frame in All Panes: Repeat this for each of the other wireframe panes, so you have the upper back framed in each of them. They should look like the image to the right.

If you need to re-center the view, ctrl-click and drag within the pane. If you need to zoom in or out, click the Select tool again so you don't have any tool selected and shift-click and drag within the pane. If you get lost, you can always right-click within the pane, Frame All, and try again.

You can also use the regular movement controls (as described in step 7 above) to frame the dangly thing in the 3D pane by moving the view to look at the upper back.

• NOTE: Milkshape appears to have a bug that will sometimes make moving within the 3d view or viewports near impossible (it still moves, but in uselessly tiny increments). If you find this is happening, right-click within that pane and choose "Reset View" and you should be able to move normally again.
  

13. Select Dangly Thing: In the top right pane, click and drag to select just the dangly thing on the back as shown. The vertices will turn red when selected.

14. Deselect Extra Vertices: If you look on the top left pane, you'll see that there are four vertices in the back which are not part of the dangly thing which got selected in Step 13. There is also one vertex in the very middle of the top of the dangly thing which is also part of the back which you need to deselect. To deselect those vertices, shift-right click on each one. It will turn from red to white to indicate it is no longer selected.

15. Check Selection: You can right-click and Frame Selection in the top left pane again to zoom in further. Your selection should look just like the image shown: 8 vertices selected at the top, 4 in the middle, 4 at the bottom.

16. Delete Dangly Thing: When you're sure you have only the correct vertices selected, press the Delete key on your keyboard (or Edit - Delete Selection). The selected vertices should disappear. If you look at the back of the dress in 3D view, there should be a nice smooth back with no dangly thing and no hole. If you still have some or all of the dangly thing showing, or you have a big black hole showing, you didn't delete enough, or deleted too much. Edit - Undo and try again.

• NOTE: We are able to delete the dangly thing off the back of this dress because it is a completely separate part. Usually, you can't just delete parts off a clothing mesh without creating holes. This is a special case, and this exact technique is not suitable for most meshes. Usually in order to delete features you will have to "Frankenstein" parts together. That will be covered in later tutorials.
  

17. Repeat for Fat and Pregnant: Now we need to remove the dangly thing for both the fat and pregnant morphs too. Click on the Groups tab over on the right and select the "body" group and click Hide. Then click on "~00MORPHMOD.1" and click Hide to unhide the fat morph. Select the dangly thing on the fat morph and delete it the same way as you did for the normal "body" morph. Hide the fat morph again when you're done, unhide the pregnant morph ("~00MORPHMOD.2") and delete its dangly thing too. When you're done, you should have no dangly things on all three morphs, and no holes either.

18. Reset Views: Right-click in each of the panes and choose "Frame All" to reset your view to viewing the entire dress again.

19. Show Only Body Group: On the Groups tab again, make sure both your fat and pregnant morphs are hidden, and just the body group is showing. You can test this by selecting the body group and clicking Hide - if everything disappears when you click hide, then it's the only group you have showing. Click Hide again to unhide it.

20. Select Waist: We're going to do a little bonus edit to this mesh - we're going to narrow the waist on the normal mesh just a little bit to make it more of a corsetted look. On the Model tab, make sure the Select tool is selected. Then, in the top right pane, click and drag a box around the five rows of vertices under the breasts. Make sure you don't get any of the vertices in the breasts or the row beneath, only those five rows. If you mess up, just click and drag to try again. Right-click and Frame Selection in the upper right pane to zoom in on those rows. You can uncheck Select and shift-click and drag to zoom out if you need to see a little bit more.

21. Scale: On the Model tab, click on Scale. Then, down toward the bottom, type ".95" in both the blanks above X and Z. Click on the button labeled Y to unselect it. These settings will make it so it scales X (left-right) and Z (front-back) but not Y (up-down). We want to move those vertices inward, not pull them closer to each other, so this is the proper setting. When you have it set up properly, click the Scale button at the bottom to scale those vertices. You'll see them shrink inward a little bit from how they were before.

22. Deselect Top and Bottom Rows: Now click on Select again. Shift-right click and drag a box around the very top row and the very bottom row of the vertices in the waist you have selected, to deselect just those two rows. You should still have the middle three rows selected. If you mess up, Edit - Undo and try again, or just drag a box around the middle three rows (without pressing shift) to select just them.

23. Scale: Click on Scale under the Model tab. You should still have the same settings as before. Click on the Scale button toward the bottom to scale those three selected rows by .95 again. This will narrow them further.

24. Deselect Top and Bottom Rows and Scale Again: Again, click on Select under the Model tab, and shift-right click to deselect the top and bottom of the remaining three selected rows. This should leave you with just the one middle row selected at the narrowest part of the waist. Again, click on Scale and then the bottom Scale button to pinch in that narrowest row of vertices just a little bit more. You've now scaled that single row three times. If you check your mesh in the 3D view, you should see the difference - it should have a nice narrow wasp-waist which looks like the sim is wearing a corset.

• OPTIONAL: You can repeat the above narrowing for the fat morph if you want. Because it's the fat morph, you shouldn't narrow it as much though - maybe by .97 instead of .95. Don't do the same narrowing on the pregnant morph, though - wearing a corset during pregnancy would not only look weird, it would hurt! It's not essential to narrow the fat morph too, however. As long as we have the same number of vertices in the same order on all three meshes, they will still work just fine.
  

25. Export Edited Mesh: Now that we've made all of our changes, we can export our finished mesh! File - Export - Sims 2 UniMesh Exporter V4.09.

26. Save Edited Mesh: You should get a Save dialog box now. Browse to your "TutorialDress Files" folder. Type a name for your edited mesh. For this, let's call it "Edited_GMDC-1" - it's a good idea to get in the habit of numbering your files when you save or export an edited version. You may need to go back and do further edits later, and by doing incremental saves, you can always have old versions if you discover something got terribly messed up along the way.
27. Save MS3D File: It's usually a good idea to keep a copy of your Milkshape document separate from your exported mesh. Usually they contain the same information, but sometimes things get messed up and you'll want to refer back to the Milkshape document itself. File - Save As and save your Milkshape document into your "TutorialDress Files" folder. Call it something like "Edited_Mesh-1" and then save it so you have it if you need it.

Congratulations! You have just edited your first 3D model!

Part 7 - Replace Model in Mesh File

Now that we have our model edited, we need to replace the 3d model in our mesh file with the one we just made.

1. Open Mesh File: Open SimPE, and open your mesh file ("TutorialDress_MeshFile.package") from your "TutorialDress Files" folder.

2. Copy GMDC Name: Click on the GMDC in the Resource List. Then make sure you're in Plugin View, and look at where it says "Filename" under "Blocklist" - Select that whole line of text in the blank and CTRL-C to copy it.

3. Replace GMDC: Right-click on the GMDC in the Resource List, and in the menu that pops up, choose Replace. Browse to your "TutorialDress Files" folder and select the "Edited_GMDC-1.simpe" which you exported from Milkshape and then click Open. You will get a popup saying (basically) "Resource Changed - Should SimPE reload it?" Click Yes. You will see the name of the GMDC in the Resource List change to the filename you just imported, and will go italic.

4. Paste GMDC Name: In the Filename blank where it now says "Edited_GMDC-1_tslocator_gmdc" select that whole line of text and CTRL-V to paste back the name that was there originally.

• NOTE: Steps 2 and 4 are not absolutely necessary for the mesh to work - it will still function just fine with the changed GMDC name, but it looks much neater and nicer with the proper name, and it's a good habit to get into.
  
  

5. Commit: Click the "Commit" button (top right on Plugin View) to commit your changes. You'll get a popup saying "Changes were committed." The name of the GMDC will also change back to how it was before, still in italic to indicate unsaved changes.

6. Save: File - Save to save your changes.

Part 8 - Test Edited File in Body Shop

Now for the moment of truth... let's go take a look at what our edited mesh file looks like in Body Shop!

1. Copy Mesh File to Downloads: In Part 7 you edited the file in "TutorialDress Files" again. Remember to copy the file from that folder to your Downloads folder again. You will be asked if you want to replace the existing file (as you already copied the old version there once). Say Yes.

2. Open Body Shop: Run Body Shop. Cross your fingers, toes, and knees!

3. Look at Your Dress: Click Create Parts - Start New Project - Create Clothing - Formal. Your recolour should be the first thing showing up, with your "TutorialDress" tooltip on it. The thumbnail image probably looks exactly as it did before, with no changed waist - that's fine, as the thumbnail is cached (saved) by Body Shop and not regenerated every time you run it. When you click on the thumbnail to select that outfit, though, you should see your changes: a narrower waist, and there should be no dangly thing on the back.

It may not be the most amazing edit ever... might look a little sharp under the arms in the back, but hey, it's your first try - it doesn't have to be spectacular, it just has to work!

• TIP: If you want to get a closer look, press F3 on your keyboard. Left click and drag to change the camera angle. Use both left and right click and drag to move the camera around. You can also press F9 to toggle showing the interface options - so you can see just your dress by itself with more room.

• TIP: You may also want to take a moment to load the game and look at your new mesh in Create a Sim too - just make an adult female sim, go to the formalwear selection, and look at your outfit there. While it's not essential for this particular mesh, in-game testing is a good habit to get into going forward.
  

Congratulations! You have just made your very first new mesh! Give yourself a pat on the back and a cookie!

Homework/Followup

Once you have successfully completed this tutorial, it's best to experiment with the techniques taught in this tutorial before moving on to more advanced techniques.

So, for "homework" your assignment is to create at least two more meshes. For simplicity's sake as a beginner, you need to make sure they are full body meshes.

Try to make one with a skinnier waist as you did in this tutorial. See if you can make the other with a fatter waist using these same techniques. Get them showing up properly in Body Shop and the game.

• NOTE: You will not be able to use the technique of deleting vertices to remove stuff in most cases, as you did with the dangly thing. As mentioned in that part of the tutorial above, it is a special case as it is a separate part. If you try doing the same thing with most meshes (for example, trying to delete the sleeves off a shirt) you will end up with big holes in your mesh, not a sleeveless mesh.

A note on uploading...

It's great to be excited about having completed your first few projects. However, these first few beginner projects are usually just that: basic beginner projects, meant more to show you that you can do it than make anything spectacular. You and a thousand other people will have done this tutorial, and there's really no need for you to upload your finished mesh (especially considering that WDS Brianna uploaded her dress without the dangle way back in 2005. So please don't upload either this tutorial's project or your homework projects to MTS2 - such basic stuff will not be accepted. Wait until you've got a bit more experience under your belt (i.e. when you have gone through the other Unimesh tutorials) before uploading.

Having trouble?

In a perfect world, everyone would follow this tutorial word-for-word and do everything just right and never have any trouble. But sometimes things go wrong. So here's a list of common problems and mistakes people make, and the most likely fixes.

Body Shop Shows Wrong Dress

If you are getting this in Part 4, Step 6:

• Did you forget to put your "TutorialDress_MeshFile.package" in your Downloads folder before running Body Shop?
• Something may have gone wrong with the linking. Go over the linking parts again.

If you are getting this in Part 8, Step 2:

• Did you forget to put your "TutorialDress_MeshFile.package" in your Downloads folder before running Body Shop, making sure to replace the existing file already there?
• Are you sure it's actually showing the wrong dress? Remember, the thumbnail will be wrong, but clicking on the dress should show you the right outfit.
• Maybe you accidentally replaced your GMDC with the original GMDC in Part 7, Step 3.
• Maybe you forgot to click Commit after replacing your GMDC in Part 7, Step 5.
• Maybe you forgot to save your edited file after replacing the GMDC in Part 7, Step 6.

Body Shop Shows No Changes

If you are getting this in Part 8, Step 2:

• Did you forget to put your "TutorialDress_MeshFile.package" in your Downloads folder before running Body Shop, making sure to replace the existing file already there?
• Are you sure it's actually showing the wrong dress? Remember, the thumbnail will be wrong, but clicking on the dress should show you the right outfit.
• Maybe you accidentally replaced your GMDC with the original GMDC in Part 7, Step 3.
• Maybe you forgot to click Commit after replacing your GMDC in Part 7, Step 5.
• Maybe you forgot to save your edited file after replacing the GMDC in Part 7, Step 6.

Wrong Dress Shows In-Game

If you test in-game and you are getting an unexpected or wrong outfit showing up, the most likely cause is incorrect game settings. In the game's graphics settings, you must set "Sim/Object Detail" to high for custom meshes to show up properly. At this time there is no known way to edit the low detail meshes properly.

Milkshape Error: "Face Count Mismatch"

This error occurs if you try to export your edited mesh and your morphs have a different number of faces/vertices. This most often happens if you have deleted too much/not deleted enough in removing the dangly thing or forgotten to remove it from the morphs. Start over the Milkshape editing part and make sure to delete the whole dangly thing from all three morphs - normal, fat, and pregnant. Make sure there are not any holes or anything else selected before you delete to prevent deleting too much.

Blue Lines/Circles in Milkshape

If you are seeing a bunch of weird blue lines/circles all over the place after importing your mesh, then you forgot to uncheck Show Skeleton as described in Part 6, Step 4. Uncheck it to hide the skeleton.

Sharp Seams/Lines Down Arms and Sides

If you are seeing sharp lines, seams, or edges down the arms and sides either in Milkshape or once you're looking at your edited mesh in Body Shop, then you forgot to uncheck Auto Smooth as described in Part 6, Step 3, or at some point you accidentally hit "Smooth All" on the Face menu. This is not fixable once imported - you must start over the Milkshape editing parts, and import without Auto Smooth checked.

Strange Transparency or Holes

If your mesh appears to have invisible parts, things showing through that shouldn't, or holes, then you probably said No when asked if you wanted to correct underweight bones in Part 6, Step 4. Reopen your MS3D file in Milkshape that you saved in the last step of Part 6. Then on the Vertex menu, select "Sims 2 UniMesh Fix Underweighted Bones V4.09" and then click OK when it tells you how many were adjusted. Re-export your mesh and continue with the rest of the steps in the tutorial from Part 7 onward.

Confused When Linking

If, on Part 4 when you open your recolour file, there are only 6 items in the Resource List rather than the correct number (8), and your file is just named "TutorialDress.package" rather than something like "5f3a3d82_TutorialDress.package" then you are likely opening the file from your My Documents\EA Games\The Sims 2\Projects\TutorialDress\ folder. That is an unfinished file. Make sure you are opening the finished file from your My Documents\EA Games\The Sims 2\SavedSims\ folder instead.

DirectX Error on Part 5

If you get a DirectX related error when you try to export the GMDC in Part 5, then you didn't get the Managed DirectX 9.0c mentioned in the "What you will need" section. It's linked on the SimPE download page under "Needed software to run SimPE" and you must get it and install it before continuing.

Mesh Replaces Maxis Original

If you suddenly notice that the Maxis outfit you based yours on has had its mesh replaced by your modified one, then you have unwittingly made a default replacement by forgetting to do Fix Integrity properly and give your mesh a new name. Go back and repeat Part 3, Steps 7 and 8, plus all of Parts 4, 5, and 7.
