   Looking for a Valve Paper
  I've been looking for this paper from Valve called "Post Processing in the Source Engine " it's not on Valves publications page. But does anyone seem to have it?Thank!   
  Sounds like you're looking for "Post-Processing in The Orange Box". Give that a look.   ;  No, that was not it :( the paper describes everything that has to do with HDR in the Source Engine such as hdr rendering it self. And it shows the hdr cube mapping method and more. This post was talking about the paper:http://www.gamedev.net/community/forums/topic.asp?topic_id=536942   ;  You're putting an awful lot of trust in the exact accuracy of the title as re-mentioned in a single post on the internet, particularly compared to what Valve says they published. I'd be more inclined to trust them. In any event, to the best of my knowledge Valve hasn't put out any papers, just done talks and tutorials. You might check out their SIGGRAPH stuff, I assume they go over everything there.EDIT: Yeah, the notes for their SIGGRAPH '06 course look pretty comprehensive.[Edited by - Sneftel on August 8, 2010 5:18:03 PM]
