I'm thinking about making a map which has a lot of moving and rotating things in it, but I'm having trouble making them work properly. First, I've got a flat square that move sup and down like a lift, using the func_tracktrain and path_track entity and func_brush. The problem is, the square and everything parented to it are flipped so they're on their side. How do I fix it so that everything is the right way up? Second, I've got a floor I want to spin like a carosel. I tried making a brush in the shape of the rotating platform and made it into a func_rotating, but in the game the brush doesn't rotate, but you kind of stutter around in a circle if you stand on it. I tried the same using a flat, platform-like prop and parented it to a func_rotating with the nodraw texture, and got the same result. How do I fix this so that the prop/brush actually rotates? I'm going to make my own props to replace the moving & rotating things, so if the solution is to make prop_dynamics will that help anyway?
