Do allow the game to swap materials at runtime, we need to know what slot is what.
For bodies, there are place holder materials found in /Cars/Bodies/Meshes.
For Fixtures, there are place holder materials found in /Fixtures/FixtureMats/...?
Fixtures also need correct material slot names:
- panel_1
- panel_2
- glass_1
- opaqueglass_1
- trim_1
- grill_1
The numbers are open ended, should start at 1, and go up to as many as required.
