I'm using Pakrat095 to pack textures into my map. I'm then using the steps below to build the cubemaps: Code: Building cubemaps for LDR & HDR(recommended) -mat_specular 0 -map <mapname>(Load your map) -buildcubemaps -disconnect -mat_hdr_level 0 -map <mapname> -buildcubemaps -disconnect -mat_specular 1 -mat_hdr_level 2 -map <mapname>(Load different level; clears texture cache) -map <mapname>(Load your map again) After all is said and done, I upload the finished product to my server and have a few people report any problems. Here's what we get. For me, the map looks 100% fine, no missing textures. For person B they only have a few missing textures here and there but most of the map-say 98% is fine. For person C they have about 60% missing textures. To say I'm thoroughly confused would be putting it lightly. Any ideas why this would happen?
