It wouldn’t need to be node based, but simply a way to ‘cook’ ‘bake’ a set of attributes into one material.
therefore removing the need to blend materials which have more attributes than you need. As is demo’d in the video.
For example,
From a list you would add what you want then ‘bake’ / ‘cook’.
add sss, spec, 2spec, textures, indirect, direct, reflection etc…
This material is now saved and can be used.
The difference being only the attributes you need are present.
This would also be awesome for brushes too.
The one thing which is annoying about materials and brushes is even though you can save them out, tweaking is more an exercise in going through seemingly endless attribute lists.
Its great to have that much customisation, but when you got what you want it makes sense to reduce the screen clutter.
Hence bake or cook material and brush.
Also being able to apply a texture as well as an adjustment curve to any material attribute is needed, if you really want shading in zbrush to be helpful.
BTW, I’m curious why a hdr envirnoment wasn’t used?
