Genesis v1.4.6 Release
Overview
This release polishes non-rigid solvers (mainly FEM, but also MPM, and PBD) and couplers. Differentiable simulation has also been greatly improved. It is now natively compatible with torch, while running about x3 faster and extended to support more setters and physics. Beyond that, the simulation is running faster than ever across all solvers, batch sizes and backends. Notably, the rigid solver and implicit FEM solver are now running multiple times faster for small batch sizes on GPU.
