So, I applied some overlays to some faces in Hammer. They show up on the right faces in Hammer, but once the map was compiled not all of them appeared. The only thing in common some of the overlays had were the ones that disappeared were all attached to objects that move. The overlays that were on static objects such as displacements showed up fine. The moving brushes in question are func_rotatingdoor and func_tracktrain. Is there something I need to do to get these to show up? Or is it not possible the way I'm trying to do it?
