Trying to install "Vive Stereo Rendering Toolkit" from Asset Store (to learn how to use right/left cam target in shader), but this plugin gives following errors:
VR is not enabled... (but IS enabled)
Current VR device is unsupported (but "We also provide multiplatform support, currently supporting Vive, Vive Focus and Oculus Rift")
Unity 5.6.3f1, Vive Focus
