So I went to go compile a quick test, and lo and behold, hammer seems to believe that each and every one of my damned overlays are touching no less than 87 surfaces. They are not.
Why is this, and how can I fix this, as it is a fatal error.
Something i found out with overlays iin the previous engine version is that if you have an overlay that overlays a lot of lightmap squares, the compiler/engine will crash. was rather surprised when i found that. Don't know if it's still applicable though.
I think it is referring to post-compile faces, not pre-compile. Turn off overlays, compile, mat_wireframe 2, look where your overlays go for any that would cover a lot of faces? :/ I could be mistaken though, as I've never encountered this myself.
I get this error on a regular basis when I make shitty cs:s maps and try to cheat-detail by making gigantic stain overlays on floor surfaces. Big brushes get cut up something nasty in compile, so set your visgroups to entities only, and fly through the map looking for some giant ones.
