I know, I’ve been having that issue too. I think I know what option in the static mesh properties you’re talking about, as I applied it to some of the moving/rotating static meshes in my second time rift.

For a first level, it's pretty good! Only thing I'd suggest is tweaking the two spinning pillars at the end; they cause weird things to happen to the camera. It's an issue I've ran into when making movable platforms myself. Changing them to not block camera might help, but TBH I'd have to look at my own rift again to see what I did to fix the issue before I can say with 100% certainty that's what's going on.
