I've had a problem similar to a few others, trying to export multiple fbx files based on an attribute that is generated on the PDG work items.
In my "Geometry Import" node, I have copied all geometry attributes from the Primitive class. I can see them when I click on each work item that's generated. But I cannot reference any of these attributes when I type @attribute_name in the Output file parameter in an ROP FBX output node. When the geometry node cooks, it renders the file with a blank name. @pdg_index works but not any other geo attributes. What am I missing?
