I'm trying to create my first new car based off the sample model 1 in game directory. I've gone about as far with this game as i can with car editor and all the wonderful cars, parts, configs that you can download. Finally got car paintable by setting materials in blender (thanks to deadbob777 guide below, Love your work!!!); finally got doors/hood opening correctly based of pdf from CMS 2018 although it definitely seemed backwards; think i got all the config text files figured out. now i'm trying to get headlight materials to work. The modding pdfs are about 30% of what you need. i've looked though posts and see people with similar problems. i've looked online and found no tutorials or true fully completed sample cars just to look at, which would be a tremendous help as the samples with the game are just bare, simple objects. A fully completed car with materials, textures, etc that i could open in unity and blender would fast forward my trial and error approach i've been going for weeks. it can be ugliest simple car in world as long as it had all necessary pieces to get a fully functional car. Any help would be greatly appreciated! Some questions:

1. do you have to download a specific version of unity? i downloaded many tell i found one that had HDRP 10.5.0 like it states in CMS mod pdf
2. do you add materials in blender or unity? i've seen mention of both. this related to next question..
3. when adding materials do you just use the name, or do you need to include some material/texture file with it. CMS pdf makes it sound liek you select the material and game imports the graphics.
4. do you have select textures as well? and in blender or unity?
5. how can you go about creating a rustmap?
6. how do you go about building the interior graphics? haven't even began to tackle this one.
