I created a material in Octane 2019 stand saved it to my Local DB. The material imports fine back into SA but gets very messed up when importing into Octane Blender. While not a complex material it was a mix material with displacement, and each of the two main materials being mixed had between 1 and 3 Layer Materials also attached, and both shaders shared some image textures.
Some of the problems:
Layer groups were not imported and one of the mix materials – instead of being attached to the Mix node as material #2, was instead placed into the slot for the Layer Material of shader #1.
Vector Displacement nodes were not imported.
A red kind of error box of “undefined” was placed into the graph.
OSL shader was not imported.
I tried creating a much simpler new test material but same results: Layer Materials were not imported, Vector displacement not imported, and an error undefined box placed into graph.
