Distribute Linux/Mac binary releases
Currently there's basically no way to test that your OSVR setup works on Linux without trying to use an OpenVR project like hellovr, as the handful of things which support OSVR generally aren't putting out Linux versions yet.
@ChristophHaag was able to distribute a working Linux version of this project for a while, but an official one would be much more useful.
For the moment I've had to use a small example game someone put together called MythgreenVR, but that was only after I asked the author to put out a linux version. Before there was no real go-to "Is my setup working?" project.
It's still there I think, but it wasn't entirely working as it was an old version made for unity 4 which I opened in the unity 5 linux beta editor and only fixed it up enough so it would not have build errors.
Since you can download unity editor for free from http://forum.unity3d.com/threads/unity-on-linux-release-notes-and-known-issues.350256/ it's not that big of a deal. The latest version of the git repository opens fine in 5.3 and there don't appear errors in the landscape anymore. Here's a build: http://haagch.frickel.club/files/OSVR-Unity-Palace-Demo-ed0c25f.tar.xz I have no HMD to test, but as it is, it ABRTs somewhere in /usr/lib/libX11.so.6 when trying to start it. for some reason.
I just saw they have a 5.4 beta build now, but this build with it still won't work: http://haagch.frickel.club/files/OSVR-Unity-Palace-Demo-4.5beta-ed0c25f.tar.xz
An official build would be nice though.
(Wow, unity editor is slow to upgrade projects and to build stuff. How do larger projects get anything done with it?)
I'm pretty sure I have seen something with a linux download recently on /r/osvr, but I can't find it anymore...
Unity is compiling the assets into different binary forms per platform as well as updating scripts et al during an upgrade. A lot of projects don't upgrade during a dev cycle. I have both a DK2 and a Vive on a Linux ws hexacore / 980ti. While I have some free time I'm willing to test your projects. Been working on my own engine and title for a bit lately. :3
