I am strugling to get any render to work. I started with Luxrender and then tried POV-RAY, getting similar error...
EDIT: I deleted the content of this question and marked this thread as resolved, because once starting the Raytracing WB instead of Render WB, it was easy to follow Yorik's manual. He even warns Windows users about file restrictions. Now the render works and I get beautiful totally black picture...
To any users who might face difficulties with render setup: Make sure you are using Raytracing WB (not Render WB) and Yorik's manual.
I'm running/testing few branches, this exactly is from Assembly3/RealHunter's branch, but I tried stable 0.17, but had even less luck.
