I compiled my map using -both to get both HDR and LDR. Afterward, I tried building cubemaps but I can't get them to work no matter what I try. I tried: Code: mat_specular 0 buildcubemaps mat_hdr_level 0 map mapname buildcubemaps mat_hdr_level 2 map mapname mat_specular 1 But that didn't work. Pink/black checkerboard on most surfaces both in HDR and LDR modes. I had a friend connect and it was the same for him, even after a mat_reloadallmaterials and game restart. I checked the .bsp with Pakrat and I do see cubemap files there. To be specific, I see files like so: Code: wood_floor01_1062_-766_401.vmt sp_0.vhv sp_hdr_0.vhv c62_-940_65.hdr.vtf There were no errors in the compile log, except for Code: *** Error: Skybox vtf files for skybox/sky_morningsnow_01 weren't compiled with the same size texture and/or same flags! Can't load skybox file skybox/sky_morningsnow_01 to build the default cubemap! But that's never affected anything before. Also, the following error came up a bunch of times upon loading the map for the first time (before cubemaps were built), but it's gone now: Code: Failed, using default cubemap 'engine/defaultcubemap' Anyone know what's up?
