I´ve trying to do them, but it doesn´t work, so... Could anybody help me?? Another problem is the Body Coloured trim, which covers many of my skins... How could I make it painted at the same time than my skin?? Cheers and thanks
For the body coloured trim, just copy the diffuseMaps and specularMaps from the stock body coloured trim's material.
Assuming the vehicle already has some interior skins, copy an existing material and jbeam for one of them and make any edits you want.
