I can not find a similar class to MeshCfg in Isaac Sim. I warp DynamicCuboid up to DeformablePrim with DeformableMaterial. The visualization stuff is not updated. Nodal positions work fine.
Thanks for mentioning keep the contact offset twice the rest offset, which I do not see in the Sim documentation.
Discrepancy Between Deformable and Visual Meshes in Python Standalone Application has a response from the team but I don’t understand what that means.
