I feel like a bit of an idiot, but here goes. I am basically finished with a map, I added env_cubemap entities. I linked them to all the textures I thought were reflective... aka glass and the chrome textures. When i load it up, i get the classic purple/black texture and turned off the specular, ran cubemaps for both ldr and hdr, then turn specular back on and still have the purple/black textures. I figured it could have been because I didnt attach a env_cubemap to all the 'reflective' textures, but even the glass and chrome were a nice transparent purple. I put a env_cubemap entity in all large rooms (didnt attach them to anything) and a few in the larger open area between the team bunkers. Not sure if this helps, but I compiled with only one env_cubemap during development and had no purple/blacks but the props would glow white until I ran buildcubmaps. after I put them in, the props no longer glow before the buildcubemaps. Any suggestions on what I did wrong?
