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.

CAS Tools is made to work with Milkshape 3D, and Sims 4 Studio is made to work with Blender. You should only have to use one and which one depends on which meshing tool you prefer. If you have more questions about how to do a project you should ask in the Sims 4 creation / CAS Parts forum. http://modthesims.info/forumdisplay.php?f=702

Please do not PM me with mod, tutorial, or general modding questions or problems; post them in the thread for the mod or tutorial or post them in the appropriate forum.

there is not any fix that solves the problem when you check the bones with the pogram that the mesh above does not encounter problems with that below because when you move the sim where the collar is you see the mesh white underneath

I can't tell you how to solve it from only a picture without seeing the meshes and textures in the package. It could be mesh problem, a texture problem, or a bone assignment problem.

In the future, please post about specific projects in the Create / CAS Parts forum: http://www.modthesims.info/forumdisplay.php?f=702 You should post here only if you think CAS Tools is causing the problem.

Again: I can't help without seeing the package and the mesh you're converting. And please post in the Create / CAS Parts forum, this isn't the place for project problems and I'm not going to answer them here.

It turned out to be a problem in CAS Tools with some full body meshes, sorry. Here is a new version, please use it to do the arms fix and it should work this time.

Hello,

I have a issue with TS4 cas tool since always, this wasn't bothering me that much at first, but now this is a bit embarrassing
The problem is when I choose a EA CAS item and a color/pattern that I've already choose for an other CC, and then click new custom content:


After that, I put my new mesh into Clone Package Editor-> Mesh Manager, save, and put a texture on it.


When I only put this CC on my mod folder, it looks great


But if I put in my cc folder the other mesh I made with the same EA CAS item and color/pattern (which look like that):


The mini skirt i've made now looks like that:


It's like the mini skirt take the mesh of the cat skirt but the textures still here But when I delete the cat skirt from my mod folder, the mini skirt will again looks good with no issue

I don't know if I'm clear because english isn't my native langage, but I've tried my best by adding few images to illustrate what I said

Thanks in advance !

The way CAS Tools works is that the name of the item (in the recolors tab) is used to calculate the id number the game uses to identify it. If you clone the same EA item and colors twice and don’t change the name at all, the two packages will have the same names and the same identifiers, and there will be confusion in the game. What you should do is give the item a new name when you first clone it.

Since I think a lot of people don’t change the name, I can include random numbers in the naming in the next version of CAS Tools, to prevent this. Thanks for bringing it up!

I run the .exe as an admin but still getting the error message "You do not have the required permissions to access the game packages folder! Please restart with admin privileges." "CAS Tools was unable to open the game packages; cloning cannot be done."

I run the program on W8.1, any idea of what can I do?

Could the game have been installed under a different account? If so you can try running CAS Tools with that account. Otherwise you'd have to go to the game files location and look at the ownership and permissions on those folders and files.

After seeing the folder's permissions one by one, I set them manually and now it seems it's working. Thanks

Hi! So I am having an issue where my original custom thumbnail that I uploaded into the package keeps getting all skewed in-game, and then when I go to check it out in CAS tools, it has changed in there as well. I've included some images to help you understand what's happening.

This is the original thumbnail I've uploaded for the Blue eyes.



This is how it shows up in-game.



And when I go back into CAS tools, the thumbnail has changed.



Any insights are appreciated. Thank you for your time!

Absolutely. I've attached it below. Everything about the mod works perfectly. Shows up in game fine. I want to upload this for others to use, or else I wouldn't care as much about the thumbnails not working since the mod itself is functioning as it should be.

Thank you for having a look!
