Matinee Issue

If I place the stock floor 400x400 architecture on a map and use matinee to move it around. It no longer provides any collision?
If I drop one on the same map and do not change the mobility from Static to moveable its fine.

I want it to act as a lift. and carry my player, however my player falls through it. any thoughts?

Thanks

Go to the propeties of the mesh in our level -> type in collision -> check if the collision is set to “block all”
