MY MOVER WON'T MOVE!? I have a brush that I've already added to the "world" that I want it to be a door. It won't move even after I added the key frames and "build all" so that they do move, the thing is that they don't and another weird thing is that when I check UEd to see if they are set up correectly they do move? Bottom line I want this thing to move when it's touched how do I do it?
