[Question] Weird prims interaction in scene

Question

Hello,

I’ve used isaac lab to simulate pick place task of robot arm. After resetting the scene, the reset performance in two environments is different. The first scene performs normally. But in the second scene, the object assets are stuck together, and the bowl on the right disappears directly after falling. It should be noted that the settings of these two scenes are exactly the same, similar to a batch. How should this phenomenon be explained and eliminated? Thank you!

Thanks for posting this. We would need more information to find out what is going on. Is it possible to remove all objects and leave the bowl that disappears to begin with? then once that is figured out, you may add objects one by one to see if there is something specific causing that behavior. For now, I will move this post to our Discussions section for the team to follow up. Thank you for your interest in Isaac Lab.
