Isaac sim surface gripper not avaliable on small objects(a sticker)

im using isaac sim to simulate a scene that a robot arm pick a sticker up through surface gripper.

I went through the surface gripper docs and successfuly implement the given example. But when i found that when the target object becoming super small, the surface gripper can’t interract with it anymore.

Does surface gripper have limitation on small stuffs? for example a 0.01 scaled default cube

Are you referring to Surface Gripper Extension — Omniverse IsaacSim?

yes it is
