I really recommend enabling the power of the Attribute node for Octane Blender, so we can use it on so many features/addons such as Vertex paint, Animation Node 2.x.
Tried to add the NodeItem("ShaderNodeAttribute") to the addon, but the Node does not work at all even though the Output socket of Attribute node and Input of Octane RGB Node are the same type (NodeSocketColor/RGBA)
I am a big fan of Animation Node, please consider adding it to the development
Thanks
