[Request] How to lock colors of vanilla vehicles? in GTA:SA Support Posted December 15, 2020 12 hours ago, SAPD Officer said: How do I edit the model? When I open up the .txd file, there are only interior and decal textures. You'd need to edit the DFF using 3ds Max or zModeler. You'd have to essentially template/UV Map the body so that there are no parts with the random colors left. This is the quick-n-dirty way to get that done, but it's not the proper way to do it.
