I've been struggling with this problem for a while now. Basically, I made a new map for CS:GO. Everything goes fine until I finally start testing it ingame. There is this one spot in my map (on the roof, in a very large room) where the wood texture is randomly black. Now, as I said, it's only happening on that one spot, rest of the map is fine.
Here's what I have tried already: - Compile without HDR - Compile with HDR - Full compile - Adding a light source near the spots (just to test if it would brighten up the area) - Moving the light sources near that area - Cubemaps
None have had any affect what so ever. Here is a screenshot of that area:
