Sherif A.Dawoud shared Shape Curl Nodes created for leaves in Substance Designer.
"I was working on a material that has fallen leaves in Designer and needed a tool to curl and twist the leaves for a more realistic look," wrote the artist. The artist noted that these nodes could be used for all kinds of thin objects: papers or cracked paint, for example.
The artist discussed all the needed nodes and showed how you can control different parameters. You can find a breakdown and links to files here.
