Vray Elements (EXR) Gamma issue


#1

Hi folks,

I have recently looked into linear workflows and read everything I could find. So far everything makes sense and things seem to be going ok…

The only issue I have is VRay render elements appear to be output with 2.2 gamma already applied, yet the RGB render has 1.0

When I take the footage into fusion, I need to add a CC with 0.454 gamma to each node, comp, then apply an overall CC of 2.2 to get the footage to match the RGB. The RGB is imported with 1.0 gamma, and has a CC with 2.2 gamma applied which matches the Max FB (this is how I would expect it to work)

My Gamma/LUT is set to 2.2 input, 1.0 output, and the files are saved with the system default select (not manually specified)

Can enyone shed some light on this? Probably missing something simple, but have tried numerous options and always the same.

VRay has colour mapping of 2.2 applied, but I would expect the Max output value to override this…

Any help would be great,
D

I think you need to check “Don’t affect Colors” in the color mapping rollout.
