One thing I find with students is they break and exploit any shortcoming of a piece of software. Ultimate testers in a way. Would be great to have a gamma 2.2 at least in the color management system so if an exr linear pipe is used, lens shader switching on and off is one less hassle as it would not be required anymore.
In our productions though I do usually write a script that switches the gamma correction off and on as a pre and post render mel when batching out an exr.
This would also allow for simpler 8bit workflows when gamma correction is rendered into image, allowing us to change gamma (not de-sRGB) for textures from the management system and still use lens shaders gamma control for output.
Seeing as 2012 is now about… Can anybody have a look into seeing if anything at all has changed? Im still a few weeks off using it. Does this system now work in producing matching inputs and outputs for sRGB or has perhaps has a gamma LUT been added?
