Collisions of Motion Controllers attached mesh

Whenever I attach a mesh to my Motion Controller component, it won’t collide with other meshes even if both their channels are set to “Block”. It works with PhysicsActors, but only that.

So if for instance I grab a bottle, this interacts only with other not grabbed bottles. Bottles in two hands won’t interact with each others, nor they will interact with static mesh actors (again, even if collisions are set to “Block”).

What am I missing? Do attached components never check collisions unless there’s a physics simulation going on?
