Blender 2.7 TS3 Tools

Blender is a free open source 3D program. With Blender and this set of tools, you can create 3d meshes to be used in TS3 as objects, i.e. chairs, tables, ect. You can get Blender 3d 2.65a here.


  • Import/export - import/export MLOD and MODL files(.s3m2b)
  • Geostate Editor - editor for geostates(multistate objects)
  • EZ Bake - bake multiplier, rgb, and specular images with just a few clicks
  • Image Loader - apply images to objects and get and idea how they will look in-game(including alphas)
  • Mesh Swap - swaps your mesh with the imported EA mesh.
  • Create ShadowMesh - makes a mesh into a sunshadow mesh by correctly sizing and positioning
  • Fix Seams - fix unsightly seams created when splitting vertices/edges(aligns vertex normals)
  • Make Glass - automagically give a group a glass material with one click(Blender viewing only)
  • Hide Bones - hide/show the bones in an object with one click
  • Add Lights - adds a four point lighting set up for checking specularity
[*]Drop Shadow Strength - adjust the strength of dropshadows


1. Download and extract the "" and put it where you can find it.
2. Start Blender and go to File->User Preferences(or press CTRL+ALT+U).
3. Click the "Add-Ons" button at the top of the User Preferences window.
4. Click the "Import/Export" button on the left, then click the "Install Add-On" button at the bottom.
5. Navigate to where you extracted the file and select the "" and click "Install Add-On". TS3 Tools is added to the the list.
6. Click the check box to the right of the TS3 Tools in the list. The importer/exporter is added to the File->Import menu, and the TS3 Tools and TS3 Image Loader panels are added to the Properties Editor under Scene.
7. Close the User Preferences window, and hit CTRL+U to save as default(if you want TS3 Tools to be there next time you start Blender).


You will need the latest QA version of S3PE to use this script. and the latest MeshExpImpHelper

1. Select the MLOD/MODL in s3pe, right click on it, and select "to s3m2b". Save the file in it's own folder.
2. Start Blender, and in the Properties editor under Scene, click the Import button in the TS3 Tools panel or go to File->Import->Sims 3 MLOD/MODL. Navigate to the your folder and select the name_filebase.s3m2b file.

When creating you new mesh, to keep sharp edges, you will have to use the Edge Split modifier. Also, UV mapped parts that are separated on the map should be split in the mesh. The exporter only exports changes made in Edit Mode, changes made in Object Mode are ignored.

To assign a new mesh to a group:

1. Right-click on the new mesh(s), the hold SHIFT and right-click on the mesh you want to replace.
2. Click the 'Swap' button.

To assign vertices to the joints:
1. Right-click on the mesh and press TAB to go into Edit mode.
2. Select the vertices you want to add to a joint. In the Properties editor, select the "Object Data" panel(button with triangle/w dots at the corners).
3.In the "Object Data" panel under 'Vertex Groups', select the joint you want to assign to, and click assign.

1. In the Properties editor under Scene, click the Export button in the TS3 Tools panel or go to File->Export->Sims 3 MLOD/MODL. If you haven't triangulated your meshes(CTRL+T in Edit mode), click the Triangulate checkbox in the export options panel(bottom-left of the file select window). Navigate to the folder you imported from, select the name_filebase.s3m2b file, and press "Export MLOD/MODL".
2. In s3pe, open the package. Right-click on the MLOD/MODL you exported from and select 'from s3m2b'. Navigate to your newly created .s3m2b file and click 'Open'.

Exclude from Export
This function allows you to specify groups to be left untouched on export. Any groups with this setting will be skipped during export, leaving the original group unedited. This is perfect for making beds, as you can exclude every group but the frame and dropshadow, and edit them without having to worry about borked normals on the mattress due to Blender recalculations. Just select the group(on at a time) to exclude and press the 'Exclude from Export' button. Do the same to re-include a group.

EZ Bake:

note: You must have a UV/Image editor window open in your scene. Also, Material mode must be set to GLSL and Shading method to Textured to view the results on the mesh. See this tutorial.

1. Select the groups you want to bake.
2. In the TS3 Tools panel in the EZ Bake section, select the size of the image, and the baking method you want to use.
3. Click the Bake button. Press ALT+Z to change to Textured shading and see results on the mesh.
4. In the UV/Image editor, go to Image->Save As to save you image. Default format is .png. you will have to open your image in an graphics program to save it as a .dds.

RGB Mask:


Image Loader

note: Material mode must be set to GLSL and Shading method to Textured to view the results on the mesh. See this tutorial.

1. Select a group. Click Open under whatever image you're trying to load(multiplier, mask, overlay, specular, or dropshadow).
2. Navigate to the image and click Open.
3. Press ALT+Z to change to Textured shading and see results on the mesh.
4. To remove an image, simply click the X next to that image.

To view the specularity(if specular image is loaded), make sure the 'Shadeless' box is unchecked and you have lights in your scene(or just use 'Add Lights').

Geostate Editor

With an object containing geostates imported, and its images loaded, select the group containing the geostate. In the geostate editor panel, select the geostate you wish to view and click 'View'.

1. Make sure you're viewing the geostate you wish to edit and switch to edit mode.
2. Click the 'Show All' button to see the complete mesh.
3. Select the faces you want included in the geostate, deselect the the faces you don't want included in the geostate.
4. Click the 'Set' button to set the geostate.

Fix Seams:

note: If you use Fix Seams, you cannot go into Edit mode with the group you used it on, or Blender will recalculate the vertex normals and undo the fix. You can use Edit mode on other groups as long as you haven't used Fix Seams on them. Fix Seams Should probably be one of the last things you do before exporting. Also, the result may not be visible, and the only way to verify that it worked is to go into Edit mode and turn on the vertex normals. But then Blender will undo the fix once you go back to Object mode, so you'll have to do Fix Seams again. :P

1. While in Edit mode, select the only the vertices of the seam(it may be easier to select the edges in edge select mode). Do the same for all groups that have seams you want to fix.
2. While in Object mode, select all the groups that have seams to fix and click the Fix Seams button. If there were no problems, 'Alignment complete' will printed in the Console.

Create Shadow Mesh:

Show/Hide Bones:

Simply click the button to hide all bones in the object, and click again to show them. Bones are hidden by default.

Make Glass:

Select the group(s) you want to make glass and click Make Glass. Press ALT+Z to change to Textured shading and see results on the mesh.
note: This does not make your object glass in-game. It's is merely a representation for viewing in

Add Lights

Simply click the button to add four-point lighting setup to the scene. (Needed to view specularity)

Importing more than one MLOD/MODL can cause problems. You should start a new project.
