With the growth of Oculus Rift fan base, the upcoming Sixense STEMs, and booming VR interest in general, it would be nice to see animations suitable for VR development. Basically that means a lot of animations intended to be used additively, and mixed and matched. For example, how I’ve been doing with OR and Razer Hydras (back on UDK, just got UE4 a few hours ago) involved top half animations, bottom half animations, full body animations, and individual limb animations, not to mentions a load of skeletal controllers. (Can’t forget the necessity of IK target bones in the rig.)
