I am still seeing this issue in ue4 15.1, are they ever going to fix this or publish a work around? I am working on my thesis where I am using Vive trackers to track both real musical instruments and a Perception Neuron motion capture suit. I am using one Vive Tracker on the keyboard to establish the initial location, and adding then I am adding a UI button to update the position when needed due to the fact that nothing I do will allow me to track it continuously without jitters. This really isnt a problem for the keyboard, but it is for establishing my tracked characters position. I can’t even attach a static mesh to the motion controller without seeing this issue. I have tried disabling low latency update, it still suffers form this issue. I don’t want to have to move my project back to Unity this far into the game, and I would much rather use UE4 and I desperately need a solution to this issue. Any help would be greatly appreciated.
