Interesting. Obviously doing something stupid. In 'Lights' set I make light groups, adding Sun and Sky. I then set the Inf light to Sun (no longer 'default now), and IBL to Sky (also not default). Then, in the SUN AND SKY SETTINGS, I set Inf to Sun and IBL to Sky. My rastionale: "... by default all lights are put in a single light group ('default') and you can only change the parameters of a whole group, not individual lights. Pose2Lux enables you to create groups and assign your lights to them, affording you more control during the rendering process."

So, then in Camera, I click on the Sun & Sky button.

I have noticed, tho, that when I go to manipulate the sun setting (gain) in Lux, it does exactly nothing. I mean, I can turn it up to 1000, and nothing happens. This is odd.
