What is the point of linking to this video when this guy blatantly has misunderstood the main point of working in linear space. People are free to work in whatever way pleases them, but spreading a false gospel is really not usefull.

ppl are free to work. but its a workflow maybe u misunderstood. first of all i dont think u understand what it is and or u havent even tried so dont bother commenting. if ur such a pro or u feeling superior please create a tutorial and than see the comments ppl like u will post :)
its easy to criticize others but u should have to guts to do something different also :)

There are some great comments/tips on the vimeo page where this video lives. Thanks to Metamesh and Heyparker!

The method outlined in the video looks like a great workaround to a specific problem I have also encountered with Vray. When the image has deep true blacks (since you are working linearly without the 2.2 gamma boost) sometimes vray cannot see edges well enough to apply its final Anti-Aliasing. That means you get hella noisy shadows, which I usually had to fight with ridiculously high AA sampling. I know I will definitely be using this method instead next time I am lighting a dark/moody scene!

Or you could just save all the trouble and check on the “adaptation only” checkbox with the gamma set to 2.2 in the color mapping rollout.

I belive the “proper way” to do it is what Rhys has described
3dsmax Gamma/LUT – Gamma 2.2, Bitmap Input 2.2, Bitmap Output 1.0, Vray Colour Mapping – Linear Multiply Gamma 2.2 and Don’t affect colours (Adaptation Only) On.
And of course if you are using Vray FB, cjeck on the srbg button to preview the effect, 3dsmax FB will look correct. And render to EXR

Chad, your absolutly right although I agree with Mark on a few points, LWF is a pain in the ass for many people and you have just highlighted a problem that has doged us pros for a while.
Thank you for your efforts and keep up the good work! I actually found this solution once but I could nevor repeat it until I saw your method of the G 2.2. In Maya I dont have the problem and it was driving me nuts!!
