Cool Plugin!
First off, thanks for whats looking like a perfect lightweight starting point for my project 
Pretty much in the same spot as you (used to be?), new to UE4 and wanting to make a cool VR game hehe. My C++ skill’s aint all that though, so yeah, this (and the provided tuts) helps alot 
So 4.14 released as i was trying your plugin & following your tutorial videos today, so i made a fork and committed some changes for 4.14, but i have no idea if its okay to post the link to my fork here, or if i can maybe somehow do a commit & pull request on your repo (dont think i can though) or how else i would go about sharing these changes with you (im a 1000% sure you don’t really need me for this, i just figured why not save u the effort) So anyway, ima just tell you to look at the forks on your repo, theres one by suicidalbanana, which is me, in that repo see commit b014874 & b621bb4 (both of earlier today) for the changes. If you need access to my fork or anything just say the word (Edit: its a pull request now)
That said, im getting some ‘lag’ in the controller movement (‘jittering’, both in your 4.13 and ‘my’ updated 4.14 version) that im not seeing when using for example the built in blueprint vr template, so i was wondering if you have any idea what could be causing that? im fairly sure its just some settings im messing up, but i have no idea which (and sadly its not the framerate settings)
Any help appreciated
