May I also suggest stickying this and any other threads that detail proper installation and where-to-get-it please? That would be VERY nice.
I had at first only found the second page, and only just an hour or so ago found out about installing into the addons folder instead of just scripts, which of course made it work .... mostly and kind of
I also had issues with the whole 'relative paths' thing, but found the solution to that here as well.
However, I've only been able to successfully render ONCE. I can supply a .blend file if desired, but it's just a simple test scene with a plane, a sphere, and an inverted cone, with one meshlight.
The one time I got it to render, I had just adjusted the 'relatives paths' thing, plus had made other 'tweaks' (sorry i can't be more specific right now), had had problems getting it the renderer to start, so I closed and re-started blender, immediately opening the test scene. I checked to see that the settings were correct, hit F12, and violla! the renderer opened and started doing it's thing. Cool. I let it go for awhile.
Stopped it, closed the console window. Changed ONLY Bi-Directional to Instant Global Illumination, saved, hit F12, nothing happened. The blender console reports something about failed I/O trying to open a closed file.
I have subsequently tried closing and re-opening blender again, immediately opening the file, and hitting F12, but it STILL won't start up again. hmmm
I'm using builds of blender and the exporter that I downloaded just yesterday.
