Hey there,
I'm using the octanerender setup window to overide the modo materials with octane materials. Im trying to use the NodeGraph node so that I can edit the materials in that standalone-type window. Sometimes when I hit "edit node" (even on some materials i've previous successfully edited), i get this message: "Error: this nodegraph or it's owner material is not used in the Octane scene, so cannot be edited. "
I have the render window open and the mesh that i'm trying to edit the materials for visible in the scene. Why is this happening, and how can I prevent it from happening again in the future?
