Is there an api that allows access to nucleus from a third party app? I am looking to send USD data from our own app which will then be loaded in Unreal using the provided connector. Looking at the docs, it looks like Omniverse Client Library is the way to go, but if understood correctly, it runs through kit which might not be available on our platform.
Yes, the client library usage is documented in the Connect Sample. Anytime you want to generate an application that talks directly to Nucleus, this is the sample to use :)
