• Playability: The layout of the room should make sense and allow sims to get around easily, with access to all the items they would want to interact with.
• Compatible Objects: Not all objects and functions are supported by the blueprint maker and if you try to use them anyway, you will end up with holes in your blueprint where objects used to be. It is highly recommended that you read through the known limitations section of the download before creating your blueprint. You should always test a blueprint in game before uploading here and refrain from using the following incompatible features:
  • Cheats or operations on objects or overlapping footprints on objects.
  • Everything in build mode except walls, wallpapers, floors, doors, windows, arches, columns, and fireplaces
  • Windows that don't have a separate resource for placement on diagonal walls.
  • Objects made in game such as food, paintings, photographs taken by sims, plants grown by sims.
• Create-a-Style: Get creative with and explore the options available with the CAST tool. Just make sure your finished CASTing works together with your room's style, makes some sort of sense, and doesn't require sunglasses to view. Generally this should mean:
  • Use textures that look appropriate on surfaces. For example, some of the EA stone textures look great applied to a couch when the colours are tweaked to look like velvet. So you shouldn't feel too constrained by the categories. But most rooms probably don't need a leopard print toilet or a wicker bathtub.
  • Your textures shouldn't be too bright/saturated, or too dark. Try to use full-saturation colours sparingly, and if you're making something black, you usually shouldn't use 100% black as it just looks like a "hole" without any dimension to it. Try using dark grey instead.
  • Avoid using some of the EA stone presets or very busy patterns in large areas, as they look very "repeaty" and can create an overwhelming effect.
  • Try to use harmonious colours that work with the room's style. Look at real-life decorating sites or magazines for inspiration.

Tip: Square rooms are easy for downloaders to place anywhere on their lot but too many of them can be quite dull. Add some architectural interest by creating a non-square blueprint.

• Floor Plans: Please make sure to include a picture of each blueprint room, taken directly from above, and zoomed in just to the room.

• Blueprint: Each blueprint upload must have a blueprint screenshot.

• Interior: You should include at least two screenshots that show the interior of the room from different angles.

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

• Size: 800 pixels wide by 600 pixels tall is a good size for the smallest pic you would want to upload. 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 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. 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.

• Credits: Custom content needs to be credited as clickable links to the download page of the items. If you can't link to a download page, then link to the creators page/the site you got the content from, and explain in the post how the items can be found. Please do not claim unknown or other creators work as your own.

• Pay Content: You may not have pay content on your blueprint/room as this is not allowed on MTS. You need to remove every pay item you have used from the blueprint/room. This includes items from The Sims Resource Featured Artists (TSR FA's for short), because of their changing free/pay status.

• Blueprint Price: Each blueprint/room must include the room price

• Blueprint size: Uploads must include blueprint/room size in your upload text.

• Game version:You must include your BASE GAME version. In TS3, lots can be installed regardless of the EP/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. Please list the BASE GAME version that the lot was built with - NOT the EP version.

• Furnished rooms: Blueprint/room uploads must be completely furnished and decorated.
