This gives me a "CASPartEditor has stopped working." error message. I'm running windows 7 if that makes a difference :/ I don't suppose there's another way to make custom CAS parts other than this program is there?

I hope I am able to figure this out and put your hard work to good use.

Well there is also TSR Workshop for making CAS items. However it's from The Sims Resource site & you'll have to go to TSR to get it. I suggest leaving your ad blocker on, no matter how much TSR wants you to look at their ads. TSRW is, as far as I can tell, the only download on TSR that doesn't try to make you watch ads or wait if you have ad block. Their "in-house" developed program is the only thing they let you download unhindered....funny that, yeah?

Anyway, the other downsides of TSRW are: it has to be installed rather than being self-contained, it runs slower than CTU, starting any new project involves clicking through several screens & subsequently waiting for the next screen to load, the import feature is as slow & clunky as starting a new project, and various operations bring up annoying dialogues asking if your project is for Sims 4 & they don't have any "no & don't ask me again" buttons to get rid of them forever.

Once you get your project opened into the workspace, TSRW runs just peachy, & is fairly straight forward. One plus for TSRW is that it has way more CAS categories available than CTU does, if you want to make something "outerwear" for example, CTU doesn't have that category. TSRW also has it's own file type ".wrk" for saving projects in progress & finished projects have to be "exported" rather than "saved".
TSRW exports as .sims3pack & has is a greyed out .package option. I don't know if .package exports were broken so they disable the option, or if it's a "premium" feature for TSR's "VIP" members only, or what, but Delphy's sims3pack extractor takes care of the sims3packs.

Don't think I'm saying this just to endorse TSRW, look at all the negative points I gave it vs a couple of positive features.
Personally I really prefer CTU by a mile, if it had all the clothing categories available, I probably wouldn't bother with TSRW at all.
But TSRW is a CC making tool & makes CAS items, if you can't get CTU to work, you can still try TSRW.

it needs to be updated

Not working anymore

This Program crash when I try to open it, Anyone know why?

So the CTU with the 3D preview is no longer working, but the No3D version will still run! It's a little less convenient but all the main functionality is still there. So grateful for this!

I'm getting an "unhandled exception unable to read beyond stream" when trying to replace a mesh for an EP item. Any ideas why that is? I've never had this problem before.

Any way to use this without having to reinstall Sims 3 to my computer? I want to extract textures and mesh from a sims 3 CC to try and convert it to sims 4. (well keyword being TRY).

However this application won't work at all unless it has sims 3 installed. Seems like a bit of an oversight...

This program is made for TS3, so yeah, it makes sense having TS3 installed IS a requirement to use it. If you want to convert things from TS3 to TS4, this isn't the program for you. I'm not a modder but I think this entire thread and comments section makes that pretty clear.

So is CasTextureUnitool compatable with Windows 10? Ive downloaded everything the way this website instructs but when I click on the application nothing happens. Granted this websites modding tutorials are ancient and haven't been updated in YEARS. Is there an alternative that people are using nowadays to mod sims games? Havent found any helpful RECENT how to mod sims info out there on the internet.

"Sims3tutorialhub" over at tumblr has a masterlist of tutorials.

CTU uses some older versions of DirectX that don't come with Windows 10. I found the solution on this page: https://thebleedingwoodland.wordpre...nitool-for-ts3/

Download the DirectX End-User Runtime Web Installer from Microsoft and run it and it will update DirectX 9c and earlier versions. I did, and CTU works now for me on Windows 10 64-bit.

This is fantastic, thank you

It works. Thank you very much!!

CTU works fine for me a lot of the time. My only problem is some package files I try to open return an error "key is not in the correct format".

Anyone know what this means or if the package files in question can be fixed? They work in game and don't seem to have any other issues
