Wrinkle Tension Shader v2

Wrinkle Tension Shader v2

This setup uses the tension of surface to give the illusion of detailed fabric wrinkle deformation.

This is a Work in Progress.

The effect uses a custom modifier and shader node group to create the effect.

• The "Tension Map" modifier stores the tension of geometry as an attribute.
• The "Wrinkle Map" shader node group uses the tension attribute to create a procedural wrinkle height map.

The heightmap can be put into a bump map node to create a usable normal map.

Things to note:

• Make sure you mesh has a rest_position attribute. This can be added using "Add Rest Position" in the shape key tab.
• This will work in Blender 4.5 or later.
• UV Map rotation can effect the wrinkle direction
