Here is what you get!

Create anything!

TSR Workshop was built to let you create any custom content you want. Be it hairstyles, objects, clothing, accessories or patterns, everything is possible with this in-house tool from The Sims Resource!

Beautiful 3D View

In order to see the changes you are doing to your creations, TSR Workshop offers a live 3D Viewport for your convenience. Changing a pattern or checking the wireframe of your mesh? You'll instantly see it!

Automatic Sunshadows

TWith The Sims 3 supporting detailed graphics and shadows, creating custom content has become more difficult. Thanks to TSR Workshop, the difficult part of creating the sunshadow meshes can be done automatically!


Are you stuck with getting bookshelves properly to work? Not a problem in TSR Workshop where a built-in Geostates editor allows you to redefine the data so books (or other objects) properly appear and disappear!


TSR Workshop lets you exchange meshes and textures with third party applications in formats such as TIFF, PNG and DDS for textures and WSO (Milkshape 3D plug-in) and FBX for meshes. Can't be easier!


Did you modify a clothing or a hair mesh and don't want to load the game to see if the morphs behave correctly in CAS? TSR Workshop has morphing sliders available and they work exactly the same as in the game!
