So how much cross over is there between VRTK and NewtonVR. Seems alot, no? I dont see anything it offers that VRTK doesnt.
Anyways, I have started to create playmaker actions for VRTK if you are interested. Because the VRTK community is so active, it is a bit of a moving target. Also, it is a HUGE package. I just started this week. Ill keep working at it little by little. (Expect me to annoy the forum with custom action questions, sorry).
Its available on my github for free: https://github.com/dumbgamedev
The 3x version matches the VRTK github version (which should hit the unity asset store in a bit). That is where I will concentrate my efforts.
