General Blender Nodes for Unity Shader Graph
Look wiki for documentation (WIP): https://github.com/Warwlock/blender-nodes-for-unity3d/wiki
I don't know how it is happening but dropdown nodes are not working in subgraphs. So Blender Nodes does not working with 2021.2.0f1. Maybe if unity finds a solution it will start work again. I think Shader Graph package have problems.
