Hello,
I’ve just updated the jme3-vr module. The pull request is pending but the integration within the master branch should be ok soon. I’ve done many refactoring in order to continue integration of various VR implementation (OpenVR, OSVR, Oculus Rift) without board effects. I’ve also updated the OpenVR underlying implementation to 1.0.9.
Please note that is now possible to specify an external native implementation of openvr. For that, you have to add the -Dopenvr.library.name=my_path_to_library option to the command line.
Here is an updated VRSample program that works with the last update of the module:
