I have a vehicle which works perfectly in all respects except for the fact that it doesn't collide with projectiles/raycasts. It collides with the player and bricks just fine. My hierarchy in Blender is as such:
|Shape
|-- detail32
|---- Armatures/bones
|---- model
|-- Col0
|---- Collision mesh
The vehicle datablock is almost identical to the Jeep's. What am I doing wrong here?
