I have an interior scene with VRaySun and VRaySky and some Skyportals, I use a standard camera but with VRay Exposure Control in the Environment Dialogue and I render either with Gamma in the Color Mapping rollout set to 1.0 or 2.2 with the Don't affect colors (adaption only) option ticked.
I like using the HSV exponential Color Mapping type because it brings back the blue colors in the sky and makes the antialiasing of the edges around very bright areas a lot smoother.
But all these color mapping related things, Color Mapping (anyone that is not Linear multipy), Exposure Control, VRayPhysicalCamera messes with the pixel values and breaks the Linear Workflow right? So when compositing render elements or, render layers/passes these need to be disabled to keep everything linear in the compositor, right??
