Those new wheels are nice!
# Franco :
BTW double sided material ingame is the same as double polies, it copies the mesh and flip normals, so.... you get twice the polycount
For that reason, I actually prefer to use double polygons instead - although that does make it easier for people to re-import my SCX files, I usually don't care that much because it helps other SLRR modders out if they want to edit my mods. It's worse for preventing theft, though.
