Gamma... again. Frame buffer.

Hi, Thomas,

I know this is a problematic point. it's some kind of limitation dur to the max frame buffer. if i remember well it was same in 0.52n depends of your max internal gamma settings.
Of course this problems disappear when using Vray VFB.

Let's say you're working with gamma 2.2 value in SR:
While working on your project, max display gamma and max bitmap input gamma is set to 2.2 by solidrocks, to match the gamma 2.2.
when you render, SR temporary set the max display gamma to 1.0, and force vray gamma (color mapping section) to 2.2 to make the render with correct gamma.
technically it's the only way to have a constant gamma while working/rendering (with max vfb)
The render in Max vfb is correct, except if you zoom in, or duplicate. i've worked dozen of hours to try to make things even more easier, but that was the limit. i'll try to work more on that point, but i've to find a trick i don't know for instance

I know this is a pain, but can't do anything against that.. that is the way it works with max vfb

Using Vray VFB completely solves the problem.

hmmm normally gamma is the same in photoshop than in max...
except if you've changes your max save options.. ?
if you use the "use system default gamma" as save options, you'll get (almost) the same gamma in photoshop... no ?
