ppf-contact-solver

This contact solver, named ppf-contact-solver and open-sourced by ST Technologies (ZOZO), focuses on realistic collision handling for cloth, ropes, and soft materials. It ensures zero penetration and prevents fabric over-stretching, solving the frequent issue of mesh interpenetration in animations. With capacity for over 180 million contact points per scene, it offers excellent scalability. A Blender plugin is provided for easy adoption in production workflows.
