I'm using a CSGPolygon in order to make a track/race road, and my goal is to detect with my car is on it. But I can't detect this collision.
Parts of the car use Area/CollisionShapes. I detect the collision with all others things, but with the CSGPolygon, not. The flag use_collision is on, the track is physically present, but to my script is like it was invisible. I have tried use raycast, but no success.
Is there any way to detect this collision?
