I’d like to be able to create a collaborative physics sandbox in Omniverse Create between multiple users. Something where multiple people could build with blocks or marbles that react physically plausibly. This Omniverse Community Stream shows something similar to what I’m thinking:
When I try to build a simple setup with a block and a floor, the synchronization between the clients isn’t smooth. For example, if I run the physics simulation on client A, and then try to pick up a block and drop it on client B, the block will jump back and forth between where it is on client B, and where I picked it up from. On client A, the block will slowly drop toward the ground. If I manipulate the block on client A, then it works fine.
I think what’s happening is that the USD reads and writes are conflicting with the physics simulation. Is there a way to make this work, or is what I’m trying just a bad idea?
Hey @cegbert, we’re somewhat able to reproduce your issue here on our internal build of Create. From what we can tell, the host of the live session has a smooth experience throughout, but users that have joined the live session run into this issue in certain conditions. For them, the sync is pretty smooth until we use the transform gizmo to force the object into collisions with other collision shapes, which results in a behavior similar to what you’re showing in your latest posted video. We’ve create a development ticket to improve this interaction. Thanks for letting us know!
