I was wanting to release a TM1 car pack at some point. Yeah I know the original textures were screwed up, especially Yellow Jacket. Me or someone else would just have to export the meshes, realign the texture coordinates, and then replace the old mesh.
I'm still having issues with the mesh importer/exporter that I'm trying to fix. I'm not 100% sure but it seems upgrading to Windows 10 causes more issues with the Toolkit. I'll try to have a fix later this week or next week. In fact, I'm going to have to redo some of the mesh import/export code but it will be better in the long-run.
The source code repository is here:
https://bitbucket.org/mrees240/toolkit/You should just ignore the mesh import/export code for now since it's going to be redone completely. I started a wiki and if there's anything you want me to add to the wiki let me know.
The TMLibrary module has all the code for parsing DPC, TPC files. WpfCore and TMTool modules are just for the GUI.
