So I tried to compile my map last night with hdr , final, and nice shadows. However, I realized after having built cubemaps that all my lights in the level were gone. They showed up just fine during a Normal compile, but not the extremely time consuming one. Heres what I did. Under the expert compile options, I copied HDR Full - final compile (slow!). I then changed the parameters for the lights_exe command to "-both -final -staticproppolys -staticproplighting -textureshadows -game $gamedir $path\$file". The first time I had tried to compile, I had added a new command with almost the same parameter, just -final came right before -game, and moved it up appropriately. However, that time vrad didn't run at all. So I was very happy to see this one work, until of course it didn't. So if you know why I've got no light and would be kind enough to explain it to me, that would be greatly appreciated.
