Picked Upload! This is a picked upload! It showcases some of the best talent and creativity available on MTS and in the community.
This is a full-purpose tool for creating CAS custom content for TS4. It's specifically meant to work with Milkshape 3D and to get around the limitations of using MS3D for Sims 4 meshes, but many of the functions can be done with OBJ or DAE files which can be used by almost any meshing program.

Here's a summary of the functions:

Cloning Tool - clone from game packages or custom packages

Clone Package Editor - working with custom content packages
  • General CAS part properties - properties applied to all recolors
  • Recolor Manager - properties for each recolor
  • Previewer
  • Mesh Manager - export and import meshes
  • Mesh Fixing Tools - fixes / changes applied to all meshes
  • Mesh Region Manager - view / modify regions
  • Thumbnail Manager - set up custom thumbnails
Mesh Tools - working with meshes
  • Auto Tool: Conversion/Auto Assignments - auto-assign bones, uv1, etc. from a reference mesh
  • Conversions: TS4/other - converts TS meshes to and from other formats
  • Separate Mesh Layers - creates an MS3D or OBJ mesh with layers separated into groups, mostly useful for alpha transparency hair
  • GEOM Tools:
    • Examine Mesh - see data in mesh
    • View Mesh
    • Combine GEOM meshes - combine two TS4 meshes
    • Clean Mesh - remove duplicate vertices
  • MS3D Tools - tools for Milkshape meshes
    • Examine MS3D
  • RIG Tools - look at skeleton data

In addition, if you click the Tools menu and Enable Special Tools, you'll see an additional Special Tools tab with various functions I've found useful for searching game packages.

Tutorial: Converting a TS3 dress to TS4
Tutorial: Converting a TS3 hair to TS4, with alpha transparency

This tool is in a perpetual state of beta, so check back for updates, fixes, new features, and so on.

As of V3.4, CAS Tools supports Legacy Edition compatibility. In the cloned package editor tab, general CAS part properties tab, there's now a checkbox for Legacy compatibility. What this does is save the package with the previous version of the CASP format. The only difference is that Legacy compatible packages cannot be set up to be created/knitted in-game. By default, any package that does not include create-in-game settings will be saved as Legacy compatible. You can also convert a package that doesn't show up in Legacy Edition to be compatible by opening and saving it with CAS Tools.

Questions, bug reports, problems, and suggestions for the tool itself should be posted here. Questions and problems concerning a specific project should be posted in the TS4 Create / CAS Parts forum.

If you're having problems, please upload the package, mesh, texture, etc you're working with and explain exactly what you did step by step. 'I tried to import something and it didn't work' doesn't help me to help you.

Updates:

9/11/2021: V3.5.3.1
- Added fingernails and toenails to exclude parts.
- Added default vertex colors for fingernails and toenails.

9/10/2021: V3.5.3
- Added support for fingernails and toenails.
- Overhauled the type filters in the cloning tab.
- Fixed the annoying 'unsaved mesh changes' message when you change a part type.
- Now changes the swatch color of eyecolors when cloning new custom content. The change is very small and serves only to keep the game from confusing them with EA eyecolors.
- Updated property tags.

6/2/2021: V3.5.2
- Fix for bug causing uv1 autoassignment to crash on clothing/accessory meshes with more than the standard two uv maps. Extra maps will be removed.
- Restored the old method of assigning slotrays from a default body mesh as an option in the Mesh Fixing Tools tab. You can now choose which method to use since the new method of calculating slotray intersections, while more accurate, may not work correctly on some meshes depending on their shape.
- Updated property tags.

1/19/2021: V3.5
Updated with full support for the LRLE texture format. Import PNG or DDS as usual and check the 'Save as LRLE' box to convert and save it as LRLE. Only diffuse/material textures can be saved as LRLE.
Added support for makeup sliders.
Notes:
  • PNG or uncompressed DDS with or without mipmaps can be imported and converted to LRLE.
  • PNG or compressed DDS with mipmaps should still be used for non-LRLE (RLE2) textures.
  • Sliders only work with makeup at this time.
  • While you can import textures as LRLE for any type of item, they may be significantly bigger than RLE2 textures and may not render well on clothing.
  • Use of LRLE for items other than makeup is experimental.

12/8/2020: V3.4.2
This is an interim update for the new CASP version introduced in the 12/7 patch. There's a chunk of new data in the new version, and I'll try to figure out what it does and update again. Note: Cloning one of the new child facepaints will NOT work.
Updated property tags.

9/2/2020: V3.4.1
Bugfix - cloned CC packages should no longer contain extra copies of bumpmaps and emission maps.

8/26/2020: V3.4
Added ability to edit new knitting/create-in-game settings.
Added Legacy Edition support. Please see the section above on Legacy compatibility for details.
Updated property tags.

7/24/20: V3.3
Added a workaround for makeup/eyecolors/eyebrows affected by the Eco Lifestyle patch. Some items may still not have an accessible texture.
Added support for new version of the CASP resource.
DAE meshes should now save much faster.
Updated property tags.

3/9/20: V3.2.1
Fixed incorrect list of flags to disable CAS Parts for Mermaids and Witches/Spellcasters.

12/17/19: V3.2
Added ability to export and import meshes in Collada DAE format which can be imported to/exported from Blender. DAE meshes can be imported directly into a package just like TS4 geoms. Please be aware DAE takes a LONG time to save. DAE is not yet supported in the separate layers function.
Will now optionally copy thumbnails when cloning a custom package.
Update of property tags to support Witches.

7/24/19: V3.0.0.1
Bugfix for program not starting on systems using some languages.
Added manual override of vertex ID in auto-conversion.

7/17/19: V3.0.0.0
Update to support mermaid tails.
Auto-assignment enhanced to support skirts with built-in reference meshes.
Mesh fixers tab redone to make it easier to fix all meshes in a package.
Corrections to rigs exported with MS3D meshes.
Import/export of TS3 meshes is removed, to be replaced with Collada .dae in a future release.
Update of property tags.
This is an interim release! There are a lot of changes under the hood which means there are probably bugs I haven't caught, and I'm hoping to get Collada support working soon, hopefully allowing users to work with meshes in Blender and more easily import from-scratch meshes.

12/21/18: V2.9.0.0
Easier import/export from/to .PNG
Updated CASP property tags and packs list for Get Famous and patches.
Minor and cosmetic changes.

6/26/18: V2.8.0.0
Added ability to import/export textures from/to .PNG
Fixed bug causing an unrecognized property tag to prevent saving changes to a CASP.
Fixed incorrect values of Exclude Modifiers option in CASP general properties.
Updated list of CASP property tags for Seasons patch.
Minor and cosmetic changes.

11/14/17: V2.7.2.0
Added a fix for transparency (SimGlass) hair which may look either very darkened or have a hard, bright shine. (Note for creators - this is caused by linking a bumpmap that doesn't exist or not linking a bumpmap in the shader at all respectively. I guess the new version rendering is less forgiving.) This fix is also in the Clone Package Editor / Mesh Properties and Fixers tab. It does the same thing as blanking the bumpmap but is done in one click. Should only be used on hairs with these problems. I've heard there may be problems with color in other hairs but without a sample package and a picture of what the hair is supposed to look like I can't test.
Fixed the vertex color correction in the same tab to maybe actually work. Updated vertex color standards.

11/13/17: V2.7.1.0
Fixed bug in Autoconversion Tool that was making mesh faces separate in some morphs
Fixed bug causing current version reference meshes in autoconversion to be incorrectly rejected as not TS4
Added a fix for distortion of dress and skirt meshes in morphs, most visible in the fat morph. (Note for CC creators, the maximum red value for vertex color seems to now be 63. According to my tests values over that are causing distortion.) This fix, along with the arm position fix, is in the Clone Package Editor / Mesh Properties and Fixers tab.

11/10/17: V2.7.0.1
Fixed failure to read textures from Cats & Dogs (and probably other packs).

11/10/17: V2.7.0.0
Updated for the new version of the GEOM (mesh) resource in the 11/8/17 patch.
Will fix arm positioning in CC that now has the arms too close to or inside the body. Open the package in CAS Tools and save as a new, fixed package.
Arm position fix updated.
Additional option in mesh autoconversion to improve results with Milkshape head meshes by retaining the original vertex numbering.
Additional option in mesh autoconversion to force manually entered UV1 coordinates.
Tag list updated.
PLEASE NOTE: This is an interim release to deal with the November patch, but I haven't tested everything. Please report problems. When reporting a problem please be as detailed as possible and if relevant upload the package, mesh, image, etc you're getting an error with. This version is a fix only and should not be used for making cat and dog CAS Parts.
I'm going to see if I can do a small standalone tool to batch convert CC clothing to fix the arms.

1/14/17: V2.4.0.0
Updated for the new version of the CASP resource in the 1/12/17 patch.
Support for toddlers added.
Support for new occult body part types added.
All meshes converted to ms3d should now have the correct skeleton.
Tag list updated.

12/3/16: V2.3.0.0
Updated for the new version of the CASP resource in the 12/1/16 patch. EA hates me.

9/25/16: V2.2.0.0
Fixed bug causing hex value error when auto-converting TS3 meshes with no reference mesh.
Fixed bug causing auto-conversion of .ms3d meshes with no skeleton to error out.
Exported DDS textures will now retain mipmaps.
Ability to view body morphs added to the CAS previewer.

Probably and probably. You can try the mesh with more than 60 bones but it'll probably distort in the game and you'll have to split it up.

Hey! I know you're working on an update, but I just thought I would add that it doesn't let you get any of the CAS asset textures from EP04 (Cats & Dogs) hope you get it updated fast, thanks!

Update - the change to the mesh resource is what's causing arm positioning to not work right, and I believe this is affecting all current CC clothing. I'm working on CAS Tools being able to fix this with existing clothing packages.

CAS Tools V2.7.0.1 is now uploaded. It can now handle the new GEOM mesh format. Opening a package with meshing in the old format and saving it as a new package should fix the arm position problem. The Fix Arm Positioning tool in the 'Clone Package Editor' / 'Mesh Properties and Fixers' tab should fix any problem arm positioning in new format meshes.

I uploaded V2.7.0.0 and then fixed the issue of Cats & Dogs textures not showing up, so be sure to grab V2.7.0.1. (Thank you spotharris)

Please report problems by describing what you were trying to do, what went wrong, what error messages you got if any, and upload any relevant packages, meshes, textures, etc you were working with. Thank you!

Please upload your package so I can take a look.

To fix the arms:
Open the package in CAS Tools
Click Save As and save a new package with the arms fixed

You mean the faces breaking apart, right? I assume you made it with CAS Tools AutoTool since I get the same results. I think I know where the problem is, but have to work on fixing it. Thanks for letting me know about this!

With this S4CASTools_2_4_0_0 version binding, it won't be like this, since I started using the new version of S4CASTools_2_6_0_1
Thank you very much! My English is very poor, I do not know whether you can understand the expression, the tool of making most of CC are very good, but there is a problem is to use the S4CASTools tool to start from me, there is a dress bound leg after the problem of uneven grid, my friends have the same problem, I had to after the split model blender is used to transfer weight to repair.

Sorry, I don't understand. Is it a problem with bone weights? Can you show pictures?

Also please be patient, there are other changes EA made in the meshes and I'm still finding out about them and working on fixing them.

Edit: You're right, the autoconversion in the older version works perfectly. I must have broken it somehow but I'll go back to the one that works. Thanks!

I should have a new version up shortly.

Edit: Version 2.7.1.0 is uploaded, with fixes for the autoconversion tool causing faces to separate and to reject new format meshes used as reference. There's also a fix for the distortion of dresses and skirts in the fat morph.

I just started to try modding for sims 4. And I want to make 3d mesh. But I never try any of these before. So I read a lot tutorial for create 3d mesh. Then I find your creation tool could make 3D mesh simpler.But I get some starter questions for how to use this tool. If im going to creat a new bottom mesh such as a penis, I guess its simpler to use this tool than blender? I read this tutorial http://sims4studio.com/thread/4324/...create-clothing . And i guess if i try to use this tool i will need SIMS STUDIO as well for importing files into this tool? Or I still have to use blender for it? If you can give me any tips, its gonna be great!
