Is there a solution for installing both mayaUsdPlugin.mll and OminverseMayaLoader.mll together in maya?
Because once I installed OminverseMayaLoader. MayaUsd plugin auto load get turn off. even if I tired to turn it on manually. I would get this error message.
// Error: file: C:/Program Files/Autodesk/Maya2022/scripts/others/pluginWin.mel line 316: The specified procedure could not be found.
(mayaUsdPlugin) //

Dear user,
How about that you can turn off the auto-load option in Maya plugin manager. Then after you start maya with UI, you can use script command mel.eval(‘loadPlugin “OmniverseMayaLoader.mll”’) to load it.
I tried your way. Maya will send out quit event. Even if comment the last line of loading our plugin, mayapy ends quickly. But if I start mayapy without any python script file as argument, mayapy enters interactive mode. Then I can copy and paste your python scripts line by line including loading our plugin. It works well. Maybe you can try it also.
I did notice some of the output errors. We will fix those errors in next release.
