Weird glitch

[RedSnappa]

I compiled Spacestation Beta 3 and the top level floors in the wings went invisible on me. It should be a gray floor like what you see on the next floor down. Also the lighting looks weird. How does this happen and how do I fix it?

I had this kind of problem few months ago but just with light sources, they were gone leaving a black hole, I think I fixed it recompiling, maybe with different options

i have tried -faster for a quick test, and -fast -samples 8 -bounce 8 for a full compile and this happened both times. I should note that the bottom and side faces of the brushes show up fine; just the top faces look caulked when they are not.

Maybe you have duplicated floor brush, try deleting it and see if another one on the exact same position appears.

In that case the whole brush would be invisible, but here it's only one side

I checked and overlapping brushes is not the problem. I have some diagonal windows; I will try removing them in one wing and keeping them in the other to see if that is the problem.

EDIT: It also seems that I have misunderstood the use of hint brushes. After removing them all, the central rooms on the top floor are fixed but the side rooms still look like this.
