Here we go again with more problems. Now with textures! How do i fix all those back spots and "Broken" Textures? I cant figure out how to edit the original car textures (If anyone is willing to give me "Long Term" help with this to get this mod finally out, Please pm me)
Hey, unfortunately the UVs of your mesh are off and do not fit the texture of the ETKi. E.g the roof:
Ok, there are at least two ways to solve the problem. It seems that you unfortunately already changed a bulk of the UVs. So you either have to redo the UVs to match the existing texture. That might be difficult since you made major changes to the mesh or you create new textures that fit to your UVs. In a best case scenario you do both. Check out this link to see how to create/modify UVs in Blender.
