I’ve tried substance designer and I love it! It’s very, very similar to Grasshopper.
A future idea would be made a “material editor for Grasshopper” similar to substance designer.
Could be possible?
I have a plug-in called GhShaderNodes with which you can create materials for Raytraced / Rhino Render in v7.
It isn’t the best implementation, in Grasshopper 2 there will be better support and integration.
How can I install in Rhino 7?
It run well with V-ray?
No, it is only for Rhino Render and Raytraced.
