Houdini Wrinkle Deformer HDA

Feature Highlight:

This deformer can generate wrinkles efficiently on geometry. Current avalible features like: Thickness/ Restlength/ Pin to target/ Self Collision Pin & map visualization etc.

The classical issue I've found with this type of deformer is generating jitters on animated geometry. This Wrinkle deformer should be able to minimize jitter issue with reasonable resistance values. Check out the breakdown links below.
