• Realism: Lots based on an actual building type or specific building should look like what it supposed to resemble (for example a castle should not just be a huge building with stone walls, but should look like an actual castle). Lots not intended to be realistic can be more fanciful, but should still have some logic to them, and be aesthetically pleasing.
• Architecture: The way the lot is built should be unique, interesting, and more than just a basic box with four walls and a roof.
• Playability: The layout of the lot should make sense and allow sims to get around easily, with access to all the items they would want to interact with.
• Roofing: The roof pieces should connect each other nicely, and not leave gaps or connect at odd angles. The roof should fit the structure, look nice, and not just be an auto-roof (or resemble one).
• Furnishing/decoration: For The Sims 2, furnishing/decorating the interior of your lot is not required however, you are required to apply walls and floor covering to each room. You may include both a furnished and an unfurnished version of your lot separately in your upload.
• Apartments: When uploading apartments for The Sims 2, they should all be at least lightly furnished - that is, all the furniture required for a Sim to live (bed, toilet, fridge etc.) without the downloader having to use cheats to keep their Sim alive.
• Landscaping: Your lot should have nice landscaping that fits the overall style, with most styles of lots having at least some well-placed plants and terrain paint, while fancier lots should have more.

The image is demonstrating using a sim in a sims2pack but the same works for lots - uncheck the unwanted content (in our example two unwanted meshes are being removed) and then click Save As and save a new sims2pack file with a new name.

Never save over your original sims2pack file - there's a bug in Clean Installer with that and you'll just end up with a corrupt file.

• For more information on using Clean Installer, please see the guide on the Clean Installer site, here.
• If you are having trouble using Clean Installer, including errors or issues with empty packages, please see MTS2's Clean Installer Support Forums for help.

Using a Mac? On Vista and it won't run? Your options are, unfortunately, pretty limited:

• You can ask a friend who can use Clean Installer to clean the lot for you (and hope they do it right).
• You can take out your Downloads folder when building lots and make them with no custom content so you don't have to worry about things being included. See the below info under "Clean Lot" for more info on why this actually may be a good thing.
• Another option is to have two or more different Downloads folders that you swap in and out as needed -- for example, one with everything you need to play your game, another one with just a few wallpapers for building simple lots, another one with medieval items for building castles, and so on. That way, you can keep track of what custom content you use while building. Keeping different sets separate can be a good thing anyway: then you don't need to page through 200 medieval stone walls in the catalogue when you're building a modern seaside villa.

We're very sorry if you're stuck in this situation and find it difficult to handle custom content in your lots, but we cannot allow users to freely upload lots with whatever content happens to have been included.

You may include items of the following types with your upload:

• Free, Redistributable Content: If a creator says that you may include their items in uploads, and the item is a free download, you are welcome to include that item in your upload on MTS. For a quick list of policies for a lot of major sites, see: Creator Policies
• Content You Have Made Yourself: If you have made content yourself that you have used, you certainly may include that item as well. If it is a new mesh you need to include all of the regular information in the text of your post (poly counts, where it shows in the catalog, etc.) you would expect for a new mesh.
• Terrain Paints (TS2): Do NOT remove any terrain paints from your sims2pack. This is the one exception to the non-redistributable policies/pay/must provide credit rules. If you remove terrain paints from a lot it can cause it to crash for downloaders. Due to this, all terrain paint creators should expect their content to be included no matter what. Please provide a link and credit for these items whenever possible, but if a terrain paint is not clearly marked with a creator's name/website, you may still include it and it will not be grounds for rejection.

If your upload contains custom content, you MUST include a LINK and CREDIT for EACH and EVERY custom content file included in the upload.

When uploading to MTS, the custom content wizard will require that you indicate the creator of each item, enter a description, and provide a link to the creator's site, profile, or original upload thread. The beauty of this system is that once somebody has entered that info for an item (or if it was uploaded to MTS originally), nobody else has do that again - it automatically gets added as credit from that point on. You are, however, responsible for making sure the links and credits are correct, even if the custom content wizard fills in the wrong information (perhaps because someone before you has entered the wrong info).

Please link to the creator's site if they have a site of their own, or if the creator posts at a forum site, link to the original upload thread or the creator's profile. You may NOT link to "ModtheSims" for items uploaded at MTS - you need to provide a more direct link to the actual creator.

We must all show the utmost respect for the people who create our content for us. Providing a simple credit and link is the least we can do to show our appreciation for being allowed to include someone else's work in our files. Nobody wants their work stolen, used without permission, or used without being credited.

Keep in mind that if your upload contains an item that someone else made, and that artist does not want their work to be redistributed, your upload will be removed at their request. You would be allowed to upload a new version that does not contain their content. For a quick list of policies for a lot of major sites (including an easy reference on ones that freely allow including their content), see: Creator Policies

Please use Clean Installer to remove all items of the below types from your file before uploading.

• Pay Items: As per the news item of November 2010, do not use pay items in your upload. A pay item is an item that you'd have to donate money to access if you went to the original creator's website. It doesn't matter if you can get it for free through a file sharing site - it's still a pay item. Don't use pay items in your screenshots either, even if they are not included. Links for "optional" or "recommended" content may be included as long as they are free sites only.
• You can use free items at TSR in MTS uploads. Any pay items - that is, ANY items by "Featured Artists" (FAs) at TSR cannot be used as their pay/free status does still change. Items by regular creators and "Select Artists" (SAs) CAN be used.
• Please also be aware that if, when uploading a sim, house, world, etc., where the custom content pictured is required, and you use an item by a creator at TSR... If that creator of the item you used becomes a Featured Artist (and thus, their work becomes pay), your upload may be tagged (hidden from public view). You will then need to switch the item to one that will stay free all the time. This doesn't apply to non-required items (hair shown in a picture where you're uploading clothing) though. If you don't like this possibility, please choose a different item to use in your sim, lot, and world uploads.
• Non-Redistributable Content: Even if an item is free, certain creators do not want their content to be included in uploads. This may be due to the content being experimental, problematic, or requiring additional instruction, or they may simply not wish to have their content distributed that way. It is your responsibility to check the policies of every creator whose content you use to see if it may be included. Items that are not clearly labeled as redistributable are not allowed - if you get special permission from the creator for such an item, please state it in the text of your post.
• If you cannot include an item, you may link to it in your post as "Required but Not Included" - if you remove it from your sims2pack file and then downloaders follow your link and install it themselves, it will show up properly on your lot. For more information on this topic, please read the Content Required But Not Included section found below.

For a list of policies for a lot of major sites, see: Creator Policies

Items You Cannot Credit/Link: All items included with your upload must be properly credited. If you don't know where something came from, use something else.

• If you cannot remember where you got an item, try asking at our Where Can I Find? Forum to see if anyone knows where it is from - make sure to provide a picture and a description so people can help you track it down.
• If you still cannot find where it was from, you need to remove it from your upload. After doing this, please verify that it is not an item that is required for your upload to look right: temporarily cut and paste your Downloads folder elsewhere and see what your upload looks like in-game - some custom content will revert to the EA/Maxis item it's cloned from when the actual item is missing, some will just be entirely gone.
• Try replacing the missing item with something else - a Maxis item or something you can include -, and in any case re-take your screenshots.
• Please see the note under "Content that CAN be Included" under "Terrain Paints" for the exception to this rule!

EA Store Content: All content by EA cannot be included in uploads. Please list it as Required but not included with a link, or as Recommended but not included with a link.

Hacks: Uploads containing hacks are not accepted. Most Sims players do not realize that lots can contain hacks. Usually they are meant for just one game version and can cause problems if users have later expansions that the hack(s) are incompatible with. Users also usually do not want hacks they did not mean to download as they can change major elements of game play in undesired ways.

Careers: Uploads containing careers are not accepted. They can cause similar problems to hacks due to incompatibility, and users generally want to download only the careers they want - not ones you happened to pack along with your upload.

Sims: Lots containing sims are not accepted. If your lot has a family in it, please remove it with Clean Installer. Most people don't want to download a lot that is infested with someone else's sims, and there's actually a lot of problems that can come along with downloading other people's sims if they have not had their memories cleaned properly before packaging. If people want to download sims, they can download them separately.

Redundant Recolours: If you scan your lot with Clean Installer and find that it has 50 recolors for the same item, remove the recolors that are not used. When you use other people's custom content, remember that you are literally borrowing it from them. Don't borrow 50 recolors when you're only actually using one. There's also no need to give someone tons more files than they need to fill up their Downloads folders - they can do that just fine on their own.

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.

• Lot size: The lot's size, for example 20x30
• Lot price: The price to purchase the lot - both the unfurnished and furnished prices
• Included custom content: List custom content that has been included within the lot file or the archive, with links to the download page. Items that should be listed as included are:
  • Sims3pack custom content items that are part of your sims3pack lot file (not cleaned out with CUSTARD)
  • Package files or sims3pack files you have manually added to the archive alongside your sims3pack lot file (usually content you yourself have made)
• Required, but not included custom content: List custom content you have used on the lot, but not included within the lot file or the archive, with links to the download page. This is a "shopping list" for your downloaders and will include:
  • Sims3pack format content you have cleaned from your lot file using CUSTARD
  • Package format content that you have used on your lot.

Every item used on your lot - included or not - must have a link and credit to the creator, and if the item is not included, your link must go directly to the place where the item can be downloaded (not just the main site or the creator's profile). This should look something like: "Wood Pattern 3 by Armiel: http://www.modthesims.info/download.php?t=511126" - what the item is, the creator's name, and a direct link to where the item can be downloaded.

If you made your lot without CC, you of course don't need to list any. A note: "No CC" or "Made without custom content" is nice to have, but not mandatory.

In TS3 lots can be installed regardless of the expansions (EPs) or stuff packs (SPs) it was built with, as long as the downloader has the same patch version or greater. EP/SP specific content will just leave empty spaces. If you've used a considerable amount of content from an EP/SP, or the items used are essential to the look of the lot, you must list it as being required.

Please list the base game version that the lot was built with. This will look something like 1.63 - 1-dot-something. For information, see: Finding Game Version

Tip: If you would like to create lots which require only the expansion packs actually for the build features you're using, you can use johna's AnyGameStarter.

• Front view: A picture of the front of your lot with all levels showing, from a low enough angle that it shows the structure well.
• Floorplans: An overhead picture of each floor.

Please remember, for your required pictures:

• No photoshopping: Do not apply filters like sharpen, contrast, etc. to the required pictures, as downloaders want to see what your lot will look like in their game, not your skills at using Photoshop.
• As packaged: Your pictures should show your lot as you have packaged it, so that what downloaders see is what they'll actually get, or need to download, for the lot to look the same in their game.

• Unobstructed views: If your lot has dense foliage blocking the view of the house.
• Comparison pictures: If your lot is based on a real building.
• Back picture: Showing the lot from the rear.
• Other pictures: Showing the rooms, landscaping, etc. from a sim's eye view, to give an idea of the feel of the lot.

• If your upload is rejected or marked as changes required and you're not sure why, ask in Creator Issues.

• If you're not sure whether your lots are ready for uploading, use the Creator Feedback Forum to get feedback on it.
