I have rather odd problem right now. Let me say first that i am no amateur of building cubemaps and i do know how they are supposed to be built with hdr and without hdr and in tf2 regarding specular being off while building. Thing is, whenever i build the cubemaps hdr on or hdr off, the map filesize or date doesn't change, aka the cubemaps won't save into the bsp. However, whenever i load my game, it looks like that the cubemaps are built and i see no checkerboard or glowing shiny models while HDR is on. It's like the cubemaps are saved to somewhere, but not in bsp. If i give the map out to someone else (i did give it to 2 people) and tell them to see if they see checker or sginy models, they do. I made a friend of mine to try to build cubemaps (exactly same steps as i did) and then he gave the map to me and the 2 people who we tested with. Result, worked as intended and should have worked like if i had build them. So the problem isn't the map either, it's my pc. I used this same pc not too long ago to build cubemaps for CSS maps and they worked ok. So could TF2 have some sort of issue regarding cubemaps or is it just my pc? Any clues how to fix this, other than using another pc to build the maps.
