I'm thinking of two ways this could be done without messing with existing cars:
1: Use the existing env/noenv flags. The extra parts would behave similar to .w files, as in they default to no env and the model flag enables it on a per-face basis.
2: Something like this, which would set env to behave the same way as on the body, including the noenv flag behavior:
Code: Select all
MODEL 9 "cars\rc\axle.prm" ;)MODELENV 9 TRUE
