Multiple textures?

ToolkitV has something like this, you’ll need to extract the ytd files from each car manually and you’ll either have to compile the scripts from github or download it from here https://github.com/Ahmedinhooo/ToolKit-V as the download link doesn’t work.

There is a paid dev tool that does it all very easily and effectively as well:

[Paid] [Updated 11/11/23] [Development Resumed] [Dev Tool] Texture Trimmer (Formerly DDSRemap).

Now, not to toot my own horn, but I also made a post about it that goes through the whole process manually, unfortunately it performs in O(n) human input complexity due to step 2 using OpenIV and needing to extract every YTD one by one, other than that there are no menial tasks in it and it implements some fixes.
