I've begun making a map for Half-Life 2 and have run into an issue: my brushes and props do not receive any specularity. I know this because weapon_cubemap is only textured without any reflectivity. I've tried manually deleting .vtf's with VIDE, building cubemaps for both LDR and HDR (yes, my VBSP has the -both parameter), my cubemaps are at least 16 units away from brushes, etc. I don't know what the problem is. All I can imagine is that VBSP generates its own cubemaps on compile, but I don't know how to get it to not do that. I’ve followed TopHATTwaffle's walkthrough for a CS:S cubemaps issue, but I did not get the same result. Any suggestions?
