This is currently a tutorial that will take some time to create but will give a better insight of the effec, modes, and different aspects of HDR through the Source Engine. Also this page is meat all HDR where it gives all information about HDR.
Current games that support HDR
- Half Life 2 Episode 1
- Day of Defeat:Source
- Lost coast
So far these are the only games that support HDR. NOTE:Haf Life 2 does not support HDR therefore if you are creating a map and want to run it in HDR it must be ran under EP1 or a other game.
