Learning from the lessons of our previous dynamic hair physics system, we have strictly isolated the evaluation process of this new system to the animation thread. As a result, its impact on frame rates and hardware overhead is negligible. In addition to delivering more realistic deformations, this new fat physics system allows us to tackle complex soft-tissue details that were previously impossible to achieve using traditional skeletal-binding physics methods. These upcoming features include:
Impact-Induced Rippling: Realistic glute waves and flesh rippling triggered by impacts, directional changes, or sudden motion.
Dynamic Flesh Indentation (Cushioning Effect): Real-time constriction and bulging effects. Players can customize the placement of clothing items like stockings or ropes, and the flesh will naturally indent and bulge around the constraints automatically.
Volume-Preserving Deformation: High-volume fatty tissues, such as breasts, will strictly maintain their total volume even during heavy deformation. This fundamentally resolves major mesh clipping and clipping-through issues.
