I think it is really stupid when you run isaacsim by the python scripts, and the backwardCompatibility checker Pop-ups and you need to click to close it every every time ! . I can set backwardCompatibilityCheckMode disabled in edit->preference->physics .
But when you run isaac sim by python scripts again , it comes back .
By the way the modify content in preference takes no effect in python script running isaacsim . Maybe you can do something to make it easier for users.
I try to config in omni.isaac.sim.python.kit and user.config.json , but takes no effect too.
Thank you very much if you could help me !
