Catching up with this thread... so far just reading but no test renders to show.

KY, yes it is loading correctly.

Somewhere early on BB explained the light box is parented to the main light, so you can move the light to wherever you want it and the light box will move with it. Or you can just increase the main camera focal length for a closer shot, which will exlude the light box in its starting position.

(Edited to add: remember to make the lights Point At your subject's focal point... head or whatever).

As far as I recall, there is an issue with rendering the back faces of one-sided surfaces - the render time goes through the roof. Not sure if this has been changed with any of the SRs.

Oh, and one more thing, for the record...

Quote - Also, my main light is neither a normal light, nor a specular only light. It is in-between. Look at its shader. The Diffuse_Color is RGB 96, not 255, nor 0. Clever? Eh? Eh?

Yes I invented it. What shall we call this sort of light?

I'm sure that's a tongue-in-cheek claim. I've been using this type of main light since my early IDL testing days, implemented my own way... see screenshot. :O)
