@Sanborn and Tea-Rexx
I dont have a lot of spare right now, please see what additional intel you can gather on your respective issues and let us know how it goes.
Sanbordn ~ Not sure, both of the nodes you mention are working great for me in 4.7.1, please investigate further.
Tea-Rexx ~ 4.7.1 plugin is working great for me, you just put in game-project level plugins folder and build your regular project .sln file as normal, please dont put it in the UE4 engine dir
