Thank you for your reply. The USD file is attached. Detaild steps: 1. Build a cylinder mesh and add defomable body to it; 2. Create deformable material and attach it the the cylinder; 3. Build a cube shape and attach rigid body to it and freezed its position and orientation; 4. Add attachment between deformable cylinder and the cube; [OCT Capsule.usd.zip](https://forums.developer.nvidia.com/uploads/short-url/lMnXv8MDiHwKzHBtgtSpNzFcGJG.zip) (293.4 KB) ---

Hi @11849519, The problem is that the visual mesh is not granular enough to match the Deformable Object. Please see this post: [Deformable Body Visualization Issues](https://forums.developer.nvidia.com/t/deformable-body-visualization-issues/330384) ---
