Great news. may I add dear friend, that for versatility, and awesomeness for working up the weapon master pack. Is to simply include the Unreal 4 skeleton, and use the IK- to root the hands, Do 2-4 anims for grips with hands. and you have something many people will be able to work with, and Kudos for an awesome pack. This is not just a personal request, as it would help me out and save an hours work, but please check this tutorial for quick and easy implementation. : RMF #01 - UE4 Tutorial - Vive - IK Bones - YouTube \Just a short amount of work in IK will really stand out and save you lots of troubles all round for just hands and different types 
Really looking forward to Oculus Touch support so I can use this and get to test it out properly
