There’s 3 other sets of nodes to consider that are already in the standards, and deployed.
I think this has some crossover with the full spec but I haven’t checked yet. I just immediately noticed some missing ones like lights.
These are listed as not core/critical but are supported and there are some useful ones, triplanarProjection for one..
These are apart of the Pixar standard and are actually in the standard package/shaderGen now, although not as clearly documented…
The layering is a bit confusing and I haven’t tried the webViewer on a model that utilizes it (all Pixar USDs are MASSIVE)
I’m not advocating the support or necessity of any nodes at this point, but wanted to make sure the list was complete and accurate..
@DennisSmolek Thank you for the informations!
There's new NPR (non-photorealistic rendering) nodes in MaterialX 1.39, which have often been requested and allow to create effects like fresnel: https://github.com/AcademySoftwareFoundation/MaterialX/blob/main/documents/Specification/MaterialX.NPRSpec.md
The current set includes the following nodes:
viewdirection
facingratio
gooch_shade
