I currently have a car controller set up in my game, and want it to leave tyre tracks behind on the ground. The ground is mesh instance.

I thought the new decal node in godot 4 would be handy, but I just can’t get it to work.
I want to add new tracks every second, but i can only get the decal to follow around the car if I add it as a child of the car.

How do I add this? What approach should i try?
