Haven't mirrored faces in a while but they should normally count ingame. I don't usually mirror any parts, just import as much exterior stuff as possible into the main child so that my body is damageable to some extent, and use the rest of the children for the interior, steer wheel and other bits i can't put into main.
Thanks. Next I'll try to get the HQ interior from Shift or Forza 3.
Btw, which child should I use for the interior? It shouldn't be offset from the car's center. Or is there any way to change child offsets?
At child ,when you export from the zmodeler,it asks you the reset to origin stuff. Or something similiar.
And i dont know how you did it,but adding an interior from another car,never fits properly.
There will be a couple bug,and you will get bored from it
