At the moment I can create a simple blender scene and render with appleseed. That much works.
If I use the blender node editor to create an appleseed OSL node tree, the “Add…” menu (shift-A) contains only the subheadings OSL_Surface, OSL_Shader, … but all of those submenus are empty. Am I missing some environment setting or path/configuration flag for this?
I’m using Blender 2.79b, Appleseed 1.9.0-beta, and blenderseed 0.8.0-beta
