The Gritty Reality of Real-Time Cloth and Rigid-Body Character Physics
summary
Chaos Cloth is a new position‑based system with practical differences: Anim Drive normalized 0–1 for intuitive stiffness control, unlimited per‑cloth collisions (NvCloth capped at 32), and geodesic tethers to reduce artifacts. Subdivision count costs ~50% more than increasing solver iterations, MaxIteration triggers only below 60 FPS, and Blueprint Cloth nodes + face‑based wind and fields enable per‑cloth control. RBANs use inertia tuning (typical inertia scale ~1.1–1.2) and the experimental Physics Control Component and ChaosCacheManager recording add procedural steering and reliable cloth caching for cinematics.
