@mordentral They arrived this morning 
They do work (tracking) and I see the “events” (SteamVR_Knuckles_Right_IndexGrip)
But they don’t output their value (Using a simple Print)
So that is confusing… they work but don’t…?
I am BP only btw.
I can’t find any documentation or other nodes of interest. (there is a 3rd party plugin avail, but I already have my pawn etc… and I avoid 3rd party plugins)
What am I missing? I hope you are not going to say “4.21”
