Bleh. So, this isn't about TF2 Mapping or the 2007 version of Hammer in general, but I'm stuck and thought I'd throw this out there to see if someone can help un-stump me. A few friends and I are putting together a full-conversion mod with the Alien Swarm base. We were trying to get color correction into the game, but we're having issues - it just won't show up. Here's the setup: After creating the color correction in the color correction tool editor by running the game with -tools -nop4, I saved the .vcc and the .raw to the 'sourcemods/mymod/scripts/colorcorrection' folder (this is the corresponding location to where Alien Swarm saves their cc files). The .raw file is named 'cc_cryo.raw'. The maps have a color_correction entity that has Lookup Falloff End Distance set to '-1' and the Lookup Table Filename set to 'scripts/colorcorrection/cc_cryo.raw'. The entity has the flags 'Master' and 'Client-Side Simulation' checked. I even tried adding in a fog_volume and setting the ColorCorrection Name to the name of the color_correction entity. Alas, we have not been able to get it to work. If there's something I'm missing or a step I skipped, please let me know. I'd love to get it functional.
