Creating a vehicle with complex collisions

I need to create a vehicle with a complex collision (with a recess).

I’ve tried many ways. Always the vehicle falls backwards.


Hi @HolToon_F ,
can you be more clear?
what do you mean by “vehicle fall backwards” ?

take a moment to express what you have done.
what you expect , and what you got

That’s what I meanv

Have you checked the vehicles collisions??
