My meshes completely disappear when I try to record a movie

I’m trying to record a short flythrough of a scene I’ve built, nothing fancy, but when the movie plays half of the scene is just not there.

The normals are fine, the materials are fine, the matinee is fine, and the meshes show up fine otherwise, its only when I try to record a movie that they mysteriously vanish.

Maybe check your bounds on the objects?
