After having spent some time working with passes, I would like to suggest a few refinements and additions.
1. a tone map pass - so that we can recreate what we see in the Octane frame buffer. Currently my understanding is that passes need to be sent out with gamma 1 and linear unclamped output, which means no tonemapping in the outputs.
2. As soon as post process pass (or other layer passed is added in render elements), it gets removed from the Octane VFB beauty pass. Is this the ideal behaviour? I would personally like to keep the beauty pass as the full render including postprocess, tonemapping and layers. Maybe we need an additional Full Beauty pass that doesnt have other passes subtracted from it.
