[BUG] XPBD Integrator zero gradients in examples

Open Lancial opened this issue 8 months ago • 0 comments

Bug Description

Target variable has no gradient in cloth_throw and softbody_properties examples when using XPBDIntegrator, so the optimization has no effect. SemiImplicitEuler integrator produces proper gradients. What is the cause of this issue here? Thanks!

System Information

Warp version: 1.7.1, python 3.11
