Problem compositing V-Ray passes with atmosphere


#1

I’m combining V-Ray passes with the formula provided:
(VRayDiffuseFilter x (VRayRawLighting + VRayRawGlobalIllumination)) + (VRayRawReflection x VRayReflectionFilter) + (VRayRawRefraction x VRayRefractionFilter) + VRaySpecular + VRaySSS2 + VRaySelfIllumination + VRayCaustics + VRayAtmosphere + VRayBackground = RGB_Color (Beauty)

However, it doesn’t look the same as the beauty.
Any help?

Do you have exposure compensation turned on? That’s a post-processing effect that will change the appearance of the beauty but not affect any of the component render elements.


#3

You mean Exposure Control in Environment tab?
Yes, Physical Camera Exposure Control, with Global Exposure value of 5.0EV, WB to 6500K, Image Control of 0.25 1.0 0.2 and color saturation of 1.

That’s your answer, then. You’ll need to do some color corrections after the back to beauty process in order to get to the same image. Or turn off Exposure Control so that your beauty render is not being post processed.

No matter what I try, still I can’t disable it to match composite.
Can you please look at the settings and explain what I need to turn off?
Unchecking “active”, “process background…”, disabling physical scale. nothing helps.
