I dont know why but when I make a simple car and set the collision bounds around the wheels and carbody these are the outcomes:
A ‘during simulation’) The carbody and wheels fly around the screen and go absolutely crazy
B) There is no collision on the wheels preset when the FBX is imported
C) It someone how magically works for no reason and all the collision is set properly and doesn’t go crazy when I simulate it
D) Playing the game ‘when either or none of these outcomes happen’ the wheels collision all collapses into the root bone and makes a unicycle type effect
Why does this happen? I have the car model rigged and scaled correctly in Blender and exported correctly as an FBX (e.g X is forward, Z is up, 1 cm = 1 cm, etc)
It seems like it wants to work sometimes and other times not at all even though I do nothing different. I can make 2 cars and rig them exactly the same way and one will do one thing and the other will do another. it makes no sense!
