Hi All, Thanks for digging deep into this topic that is so confusing and so important at the same time. I accept the theory that the inputs needs to be linearized (textures and rgb values) to have a correct render in linear space. I understand as well that the file itself (32 bit exr/hdr/ etc etc…

good thread, thanks all for discussing this stuff…those settings could be welcomed on the spot3d help pages, no?
