Your CAS content should have a swatch of its own (unless it is a default replacement) and its own thumbnail where appropriate.

• Clear: Textures should be crisp - not blurry or pixellated and make sure to turn up the Texture Detail setting on your in-game graphics options for picture taking..
• Brightness: Neon or bright colours are fine, but don't go too bright - 80% saturation is usually plenty for even neon textures, but more just looks blinding!
• Black and white: Items meant to be black or white should use very light grey and very dark grey textures, not pure black and pure white. See: Tiptorial: Making black and white clothing the right way
• Highlights and shadows: Even skin-tight items should have some highlights on areas like breasts, tummy, butt, knees, and thighs, and should have shadows on areas like underarms, crotch, middle of the back, etc... See: How to add shadows and highlights
• Details: Details like buttons, seams, shadows, bellybuttons, etc., should be in the right place and look like they fit the shape they're texturing. If you use photos as your texture base, you may need to adjust these significantly, and choose your photos wisely.
• Seams: Seams on your textures should look fairly natural, and not out of place. Avoid using repeating patterns which have seams in them. See: Tutorials:Seamless Textures
• Bump maps: Bump maps should fit the item well, and not just be a desaturated version of the regular texture. If you can't view bump maps yourself, you should make a neutral bump map. See: Tiptorial: Bump Maps for more info.
• Adult skintones: Skintones uploaded to MTS must be "barbie" below the waist - that is, you may include nipple details but not genitals or pubic hair. Such items are welcome at our adult site, Sexy Sims.
• Choice of mesh: If you're retexturing a mesh, the style of textures should match the mesh shape (for example, a tuxedo on a skin-tight mesh doesn't make much sense), and the mesh should be one that's decently well-made.

If you have made or edited a 3D model (mesh) to make your CAS content then you also need to think about:

• Polygon count: Your poly count should be reasonable for the item, usually in line with the poly counts of a similar item from the game.
• Morphs: Morphs should work properly.
• UV Map: The texture/UV map should not be seriously distorted.
• Mesh shape: The mesh shape should generally be fairly realistic - looking as if it's subject to gravity, with body parts done in a believable sort of way (for example, no boobs the size of minivans that levitate around the collarbones, please).

Package files you have created with a tool such as ColorMagic or Sims4Studio.

Please note that if you are uploading recolours of your own mesh, you need to upload the mesh to MTS as well. Please don't link elsewhere for people to get your mesh, unless it's already on MTS. You will need to provide additional pictures and information for a new mesh upload.

For instructions on compressing your files into an archive, please see: Creator Guidelines: Creating Archive Files.

• Do not include multiple archives with the same contents - that is, please don't put your files in both a .zip as well as a .rar because some people only want .zip files. Choose one format.

• Do not double-compress your files... a .rar file inside another .rar file (or any other archive inside another) doesn't compress it anymore, and it makes it so we can't see the contents without downloading, and also just makes an extra step for the people downloading.

• The file size limit on MTS is 50 mb. If you exceed this limit you will need to split your archives. This should probably never come up except for large worlds for The Sims 3, or huge sets of smaller items.

• If you have made a new mesh, you need to include polygon counts, which you can find by checking your mesh in your 3d editor.
• If a mesh is required then you must provide a credit to the original creator, mentioning them by name ("Mesh by Soandso") as well as providing a clickable link to where the mesh may be found. You should make it clear that the mesh is required but not included, if you have not included it with your files, so downloaders know they will need to get it separately.

Upload information

Please ensure that you fill in the search parameters correctly when you upload.

For all CAS uploads, we require the following info to be listed in the description unless you include a CAS screenshot showing where the item can be found.

• The age(s) and gender(s) your creation(s) are for (example: "This works for young adult, adult, and elder females.")
• The category your creation appears in in CAS (example: "This outfit shows up in the everyday and formal categories.")

• For recolours of the same texture, pick a colour and show at least one full size picture, and you can show swatches of the rest of the colours (see image to right).
• For recolours of different textures you need full size pictures of everything.
• For new hair or clothing meshes, you should also show your creation from other angles - at least the back and sides. For body/clothing meshes, you should show how the fat morph looks, and the pregnant morph, too, if you've done a pregnant morph.
• For skintones: If you're uploading a skin, please blur or otherwise cover the butt crack and crotch of both genders, and the female nipples. Sims can wear extremely skimpy clothing, or you can blur or cover those areas in a photo editor. Take several pictures of the bodies and faces, showing the different colours (if you've made more than one), and the different ages and genders.
• Thumbnail that shows all the swatches of your recolours, if you haven't included full-sized pictures of all the recolours.
• CAS Thumbnail: If you have not listed the age, gender, and CAS category of the upload in the description, we need a screenshot showing the thumbnail in CAS so downloaders can figure out where to find your item.

Keep the following in mind for your screenshots, especially the required ones:

• Size: 600 pixels or more on the smallest side is a good size to aim for. Your images can be up to 2560x1440 pixels, and 800 kb, so you have lots of space to work with!
• Lighting: For most things, it's best to take pictures in an interior room with good lighting. For TS4 CAS you may want to take the pictures OUTSIDE in daytime. For lots, pictures should be taken during a nice sunny day, for floorplans, take the pictures with the lights ON.
• Clarity: Neither blurry, nor pixellated/crunchy. Do not size up small pictures to make a large one as this will blur them, and make sure not to use too much compression/too low quality when saving your images.
• Distance: Take your pictures so that your creation fills the screen without anything cut off at top or bottom - neither zoomed in too close, nor zoomed out too far.
• Distortion: If you resize your images, retain the aspect ratio so they don't get stretched or squashed. In TS2, make sure "use square pixels" is ticked in your game options.Take care when zooming in and out with the camera that you do not create a fisheye effect on your pictures.
• Photoshopping: Do not apply filters like sharpen, contrast, etc. to the required pictures, as downloaders want to see what your creation will look like in their game, not your skills at using Photoshop.
• Attached: All required images must be attached directly to the MTS upload, not just inserted using the img tag, so that even if the pics get deleted from your Photobucket (or other host), the upload on MTS is still complete.
• Show all items: For most areas, if you are uploading a set, you must take all the required pics for each item in the set. If there is an exception, it will be noted.
• Picture limit: You may upload up to 100 pictures for a single upload thread, so feel free to add some additional pictures just to show off your work to its best. Of course, keep it reasonable - nobody needs 50 pics to show off one sim or hair.
• Inline pictures: Inline pictures are those that use the [img] tag to show up in with the description text. So that it doesn't take too long to load, please keep this to no more than 4 pictures done inline, unless you put them inside an [infobutton] tag. To do this, see our guide on post formatting.

Please remember, for your required pictures:

• In-game: Since The Sims 4 renders the clothing pretty much the same as in-game, it's totally fine to show your recolours or mesh in-CAS. We do however recommend it for presentational purposes to show them on a lot anyways, but we won't ask you to change it if you decide to show it in CAS anyways.
• Uncovered: You should take pictures of sims modelling your content in basic poses without arms or legs in the way, use short or pulled-back hair on a clothing model, no bangs/fringe obscuring makeup or eyes, nothing in the way of the view of your content (except for skintone censoring, if you've made a skin).

Tip: You may, of course, include additional other pictures presenting your creations however you like, and you can get as creative with them as you want.  :)
