Hi,
Up until now I have been using the NRSDK. However, I came across the NRSDK XR Plugin Introduction in the documentation:
https://nrealsdkdoc.readthedocs.io/en/v1.6.0/Docs/Unity_EN/XR/Introduction.html
Also this forum post:
I’m a bit confused as to the purpose of the XR plugin. How does it relate to the NRSDK? What is the Nreal XR Plugin used for? Should this be used instead of the NRSDK for certain applications?
