Physic transformer car


I’m doing a car in physics, using physics joints and adding torque to my wheels in order to move my vehicule.

It works if the components come from the same actor… (my car move)

BUT, i want to add some specials fonctionality to my wheels (like being destructible / react to hits), so i made my wheels as detached actors, then i spawn them and attach the static mesh components from this actor to my main car body using the set constrained components function from the physics joints.

Then my car cannot move anymore

The wheels cannot turn if they touch the ground, but they can if the do NOT touch the ground.

I know it’s a very specific problem, but any tips could help!
