Clipping issue #482

Closed Vivi0928 closed 1 week ago

Vivi0928 commented 4 months ago

I encountered a clipping issue while using simulation. For example, when a cube is dropped in free fall onto a table, if the drop height is too high, the cube will pass straight through the table.

Ah yes - this is due to details for the underlying physics simulator (mujoco) and how it performs physics. You can read the docs I linked for more detail; but I think w/ the default configs, this is expected --- one way to resolve is to just not drop it from super high; another is to decrease physics timestep size, but w/ enough speed it'll go right through. Closing for now!
