The Designer Twins: TouchDesigner + Substance Designer
“The Designer Twins: TouchDesigner + Substance Designer” is a project built with TouchDesigner, featured in the Derivative community showcase in 2021.
Substance Designer is a material creation program that doesn’t require knowledge of GLSL. There are loads of free resources for artists and designers which include PBR materials. If it makes sense in your pipeline to use them then have at it (after reviewing the terms of each resource).
