Sure! We haven’t been testing it for long yet, but so far we had some issue in finding session with both the Oculus and Steam backends (also the pre-built version many times doesn’t find any session… my guess is too many people are using the SteamVR test ID at the same time with other applications and UE4 only retrieves a subset of the sessions)
Also, when using the version 3.0 I see a strange green reflection in SSR if enabled (let aside SSR is not the best thing in VR, this was not happening before 
Reading the release notes I get Oculus Avatars need a separate plugin release to work with 3.0, is this correct? Do you have any ETA for it?
Thanks in any case for your great work!
