Hi all,
I've seen the conversation about linear workflow started a couple times on here. I've spent the last couple days trying to understand this with little headway. Am I right that Vray is already set up for this workflow but that some extra settings are needed? Any help or corrections to my understanding would be greatly appreciated. It's likely I'm over-thinking all this.
Here's what I think I know:
1-gamma correction is needed to make sure images are bright enough and color correct when displayed on a monitor.
2-most images used for diffuse textures that are pulled from internet already have gamma correction applied.
3-the goal with linear workflow is to A: remove this gamma correction from all textures prior to rendering and B: to apply gamma correction only once, globally, at either the render stage (inside Vray) or post-production stage (inside PS.) (NOTE: bump, specular, and displacement maps do not need to be adjusted for linear workflow. They only need to be set to RGB "color space" to preform correctly.)
Is this right?
How do I de-gamma my diffuse bitmaps? Do I set the "gamma correction" value to .454 inside each material's texture editor? Or do I do this in the COLOR MAPPING roll-out by setting the "Input gamma" to .454? Or do I check "Correct LDR textures" and "Correct RGB colors?" None of these? All of these? IDK
What about on the output side of things? It would be great if someone had a pic of their COLOR MAPPING settings for this.
Also, do any of these setting change if I'm outputting separate channels to composite later in PS? I've read saving as a tga. file is best because it's 32 but, unlike exr, you get the full range of adjustment layers in PS.
Thanks for the help.
