There is a default head-lamp that you can shut off if you don't want. See the documentation for "head-lamp" under "light basics". Otherwise, from my understanding, the light calculations follow the...

Problem solved. Truly sorry for the trouble.
Turns out that Vizard couldn't render at the full 120 Hz (hitting only 60 Hz instead), because of a bandwidth problem that I'd forgotten had arisen in...

stereo rendering problem/bug
We would like to use frame sequential (active) stereo with shutter goggles to study the perception of depth. (Currently, we are using red/green anaglyphs.) Unfortunately, there seems to be a bug in...

Well, that's not really true. The ghosting is related to the filtering properties of the glasses, so those glasses with a better bandpass filter and good cut-offs would be better. We even notice a...
