No more volunteering Kyle.
This should be done professionally, by someone who has the know-how, time, expertise and availability to do this work properly. This also includes getting the system’s features developed correctly so this work can be done right.
Having things done this way is not a freebie, it’s not a quick job, and it’s not cheap, but it’s usually a wise investment.
I suggest you guys ask @Holo if he’s available, and get him to quote you a project for it. His head is already in the space: PBR materials and WIP rendering feedback
You could do this yourself too of course, or you guys could do it together. He also seems to me the only one that has both experience and willingness to put up with Raytrace/Cycles. So McNeel could have a really good chance here to have experienced designer/s to design the system, and then work with their own experienced developers to develop those designs/requests.
I’ve said this before and I’ll say it again: It’s time you guys stop relying on amateur, improvisational, side-project, divided-attention, and volunteer work for Important parts of your own development. McNeel has a proven 20 year track record that this approach has continuously failed miserably, on repeated attempts, when it comes to rendering and visualization. And I see the same behaviors and approach still taking place.
Like Einstein once said: The definition of insanity for him is doing the same thing over and over again and expecting different results from it.
