DEMs incompatible with model mesh collisions #657

Open oliviaseed opened 2 weeks ago

oliviaseed commented 2 weeks ago

When using a DEM (such as any of the DEMs in gz-sim) and the recommended collision detector (bullet) in conjunction with models that use meshes for the collision, these models fall through the ground.

Following video is with bullet: https://github.com/gazebosim/gz-physics/assets/77899097/9c23a988-20f6-4759-b2f5-410aa89fbf1b
