(1) The glitches shown in this picture are not visible in the game, they do not give out any errors while in valve hammer, and they do not give out any errors while or after compiling (in the log file). Lag is not an issue in game either.
The pipes that has been translated in an angle (usually unacceptable by Valve Hammer) on the other hand, does not give out any errors while in valve hammer, and they do not show up as glitches in valve hammer. But while in game, under direct light, the glitches appears greatly. (These pipes was not modified after translation, clipped or otherwise).
The problem occured after I changed the pipes angle.
HLVIS seem to crash while processing LeafThreads, so I have to end the process manually in windows or else hammer will crash. The message "Warning: No vis information, direct lighting only." is displayed in the hlrad information (of course).
I THOUGHT those pipes were my problem, but after I had deleted them, the hlvis problem still occured. I also tried to delete the target_mp3audio entity that I had placed in that area right after I fixed the pipes, but the problem still occured. I also tried to delete the last light entity I edited in the room (I only changed the color a bit).
If the map visability procedure won't execute properly, what could be the source of the problem? The map is not too big just yet, I deleted the last three brushes and entities and tried to compile again but the problem was still there.
There are NO errors displayed in valve hammer, NO errors in the log. hlvis just seem to be mocking me it seems.
