I made a Mesh through Chaos. I added a convex collider and I enabled physics. Its collision preset is a PhysicsActor. But when I start the game, nothing happens. It’s frozen in midair. It colliders with the player, but isn’t affected by force or gravity.
Found the issue. The mesh, created by Chaos plug-in, was default to “Use complex collisions as simple”, which meant the complex collision I had set was being replaced by the inexistant simple collision. Physics can’t happen without collisions, so they froze mid-air. Fixed by using “Complex and Simple” or by adding a simple collision as well.
