So here is my first screen capture video. It explains my linear workflow for Vray. I apologize if my energy level is not to your liking (my daughter was asleep in the next room). Next time I’ll sham-wow it up.

Is there a difference between gamma correction and linear in the color correction? It helps if you use affect color to help clean up shadows when gamma 2.2 is applied.
Thanks for taking the time to show us your work flow. I was wondering if there is a difference between adding a color correction node to correct materials and colors in material editor compared to max handling that for us? I have been using max 9 and am referring to customize/preferences/gamma and LUT tab. In there I have the gamma set to 2.2 and also select the affect color selectors and affect material editor. This way when I import a bitmap in the dialog box under gamma I choose override and tell max that this texture already has a 2.2 gamma correction on it to prevent the texture from brightening up when I render. This also allows me to avoid correcting even diffuse colors in the material editor. The problem is I am not all that sure if this is the same style work flow that you use and was just looking for some clarification to correct my work flow. I have a tutorial that I learned my current work flow from I can link to if my explanation of my process doesn’t make sense.
Thanks!
I tend not to use the global max gamma control as it is not saved with the scene and if you are rendering to any kind of farm, you have to make sure that each machine is set up accordingly. aka it’s a pain in the ass. This has apparently been fixed in 2010.
Ah Thanks!
Really nice explanation but there’s one small thing you seem to miss in this work flow. You can check “Don’t affect colors (adaptation only)” in color mapping tab to tell vray how to sample your image. For example: if you set gamma to 2.2 and turn Don’t affect colors ON Vray will sample your image according to 2.2 but the tone range won’t be affected, so you still get unaffected 32bit output but with a correct sampling. No need to oversample lights, materials and noise threshold.
Great tip! Thanks!
