gamma correction, to bake or not to bake?
I've noticed while moving to working in LWF that, in low light conditions, rendering with a gamma of 1.0 in vray gives noticeably reduced quality to rendering at a gamma of 2.2 .
I assume this is because the render engine is working in a gamma corrected colour space and has more mid tone light to work with, hence better sampling etc, would this be accurate?
If I lower the Clr threshold in the AA settings i get a clean image again, not a problem in a small scene but in a bigger one it will increase render times so if i render with the gamma baked in and simply apply a 0.45 gamma to the saved 32 bit files, will this cause any issues later on with compositing ect?

in the Vray Color mapping settings, set the Gamma value to 2.2 and check on "Don't affect colors"
This with cause the adaptivity to be measured in gamma 2.2 space so that you don't end up undersampling the darker areas of your image.
