@gaojunning i am just another user, but what were you expecting to see in the menu for OmniGraphs specifically? this is what i have under Utilities via workstation installation on Windows:
I am looking for : Common Omnigraphs —> Differential Controller
which is a controller template ( with these 4 components connected and configured:
On Playback Tick,
Differential Controller,
Articulation Controller,
MakeArray)
I know, there’s another way to build the complete controller from 0 using action graph, but it would need some works.
So I am just wondering to find the template shown in a isaac sim course. (course link: Course | NVIDIA )
