At the moment I play around with the 3 (object-) lights Indigo uses.
So I did a quick scene with 3 spheres, each lighten up by one of this lights,
with default settings to check how they behave...
from left to right: Peak, RGB & BlackBody
(RGB gets a Red light to see it better)
all 3 lights:
only Peak & RGB:
only RGB:
Because Lineare ToneMapping doesn't work form me in v0.6T1 I couldn't Test,
But my idea about this, is that Rainhard kills it!
