BTW for those new to my blog this is my little game engine you can edit map, game components, and materials; or update lua scripts and shaders via a cute HTTP interface and/or sublime text 3 while someone plays! Makes for interesting VR experience, and that social stuff people blah blah blah about. Right now it's Linux only, because it's a hobby project in my spare time. Looking for an artist for a possible public demo / release this year. ;)
OK I hacked in the ability to capture the HMD backbuffer and camera image at the exact same time real quick with a button press. I suggest listening to The Cars - Good Times Roll while viewing.
