I really don't know what I'm doing wrong here, but whenever I try to test the world I'm editing, there's a lot of invisible geometry that extends above the actual objects. I'm not sure what's going on here or how to prevent it. Is this a result of objects that are overly altered and warped? I'm really not sure how I can prevent this. It seems to affect sphere objects most of all perhaps. Any tips for how I can proceed? I'm at a loss.
