Hi, so my query/problem is a disparity between, the results of a PS comp with VrayRenderElements, versus the RGB_color.
With the RGB_color element on top of the stack, turning it on/off reveals differences in the highlights, that have no obvious cause. Does anyone know why?
Elements in the comp are:
+ VRaySelfIllumination
+ VRaySpecular
+ VRayReflectionFilter x VRayRawReflection
+ VRayRefractionFilter x VRayRawRefraction
+ VRayRawGlobalIllumination x VRayDiffuseFilter (copy)
+ VRayRawLighting x VRayDiffuseFilter
I'm pretty sure my comp is correct, but perhaps this is a quirk of VRay or PS that requires some kind of workaround? (Maybe I've overlooked something :/ )
(The 3ds Max process shouldn't make any difference, because, so far as I know, the RGB_Color element is the "Beauty pass" and the correct combination of elements can be used to reconstruct this exactly. However, just to elucidate, the procedure was:
Linear workflow.
Lighting = 1 x VRayLight Dome, with small blurry HDRI (set to invisible)
Environment Map.jpg (in Environment and Effects)
V-Ray GI Environment (skylight) override is black
Window Glass is Excluded from DomeLight.
Exposure Control (in Environment and Effects) is left as .
No Effects, no Atmosphere.
No D-O-F on VRayPhysicalCamera. f8, 1/6, 1600
Elements were saved as 16bit EXRs, from the VRay frame buffer, using the "save all image channels" button.
Load Files to Stack: Folder added in PS.
ProEXR plugin for PS installed; gamma is fine.)
But don't let that sidetrack you; back to the question:
