Good Day…
It would be great if you sold special licences for us to package vorpx with our DX9 to 11 3D games on steam.
I run a community website for a game engine called coppercube which does not yet have good VR support…It has only got minimal support for older versions of oculus rift.

In any event, most indie developers that use this 3D engine love it as it is low cost and easy to use.
Maybe you can create some kind of royalty based licence…If it is not too expensive many of us indies would probably buy it.
