Thank you for your time. I had installed the patch you mentioned. v1.0.1

What I found was the problem to be was - in the Isadora Plugins Folder, under the properties for the RokokoStudio Live Watcher, Skelton Decoder etc, the various .dll and .qtr files, their Attributes had been blocked by Windows 10 because "it was downloaded from another computer". I checked  on the unblock option and hit apply and - magic -  they are talking to each other. 

Big thanks Isadora Community. 

As an aside Rokoko tech support advised to use Json in Rokoko's Livestreaming. That was wrong for me. JsonLz4 worked not Json.They also advised to avoid Mac.....??

Thanks Again

Yes.  I have however invested a great deal of time learning UE4 to this point (not to mention sizable investment in 3D model assets).  Although a good deal of basic concepts will transfer to Unity, having to relearn 3-years of investigation makes me pause.

I am also waiting to see what happens with the Epic-Apple issue.  If support continues to fall away for Apple from Epic... I will switch to Unity.

As a Dance tech guy I am amazed by what you have achieved Andy. Thanks !
