[Bf-cycles] Some suggestions for nodes' interface revision in PBR times

[Stuart Compton]

I add my vote to this. I lurk here, but I’ve been an artist, technical artist, and (sometimes) coder working in CGI for film and games since the 80s (mostly games). 99% percent of workflow is linear & sRGB. 

Options are nice, but please acknowledge overwhelmingly common workflow and bury the exceptions in ‘advanced’ (or some such). Even small changes like this make workflows significantly faster for repetitive actions in production workflows.

A voice among many, but a voice.

And I don't think I've worked on or even heard of a colleague that had worked on a production in five years or so that hasn't adopted a completely linear workflow. Anecdotal, sure, but I would be very interested in hearing of a pipeline that wasn't linear or sRGB based in 2017.

In a PBR workflow, most of textures should be linear (roughness, metallic, normal map, ambient occlusion etc) and only albedo/base color is usually a sRGB bitmap. Therefore, we need to perform 2 clicks over the majority of textures we import... A better approach would be to have just a check box for "[  ] sRGB", like in Unreal. If it is checked (default), color space is gamma corrected, if it is not, it is linear. Believe me, when you have a scene with dozens of PBR material, this is a huge time saving.
