Good to see here!
I installed the plugin via the Omniverse app so I assume it installed cleanly although I could try installing again. Initially I started Maya 2020.4 and loaded the omniverse usd plugin and it failed to load with a generic plugin initialisation failed error. I searched the forums here and found a thread about first unloading the maya-usd plugin which as on auto-load in my case. So, I turned that off and restarted Maya and verified that maya-usd plugin was not loaded anymore. Then I tried to load the omnivores plugin and ran into the error message attached in my first post.
Wondering if there are other components that also need to be installed or if the maya connector should be enough.
