Blender 2019 (2.79 and 2.8) not correctly importing materials from Local DB.

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.

Material from Stand Alone - saved to Local DB: Material imported into Octane Belnder from Local DB:

Just did some more testing. This time I created a simple layered material directly in Octane Blender (2019 - 18.4) and saved to Local DB. But Octane Bender can not re-import the Material Layers correctly. Again, they are absent - Octane Blender sees those material layers as undefined. The material, however, is correctly saved to the Local DB because Octane stand alone has no trouble importing it intact.

Thanks for your report. We confirm the layered materials issues and will fix them in the next build.
