Complex collision on moving objects

Perhaps I’m reading this wrong.

It reads to me that if using complex bounds as simple you can’t simulate an object physically. I appreciate that we’re on some fairly complex territory but proprietary game engines I’ve worked on and in in the past have allowed moving, simulated, complex meshes and gameplay has used this feature extensively.

If I want a moving physically simulated object can I get the player vehicle to collide with the complex bounds?

Surprised this hasn’t been answered yet, this would be highly useful for my current project with physics barrels, they stop rolling with the simple collision but complex collision would seem to make it smoother but I can’t test it or use custom collision for it, for some reason.
