Nice one Fran, Is the light embedded inside the large sphere? If you used the "default" settings of the scene/ibl, thats the same thats included w/ the "robot in ibl room 9" scene, part of the Bryce 6 content. At 1st i didnt understand why the atmosphere was set as so, but its making more and more sense now...

On yours Dave, I cant tell where you placed the lights... And at 25% intensity, thats a bit high, so Im wondering what hdri map and settings you used, just from having 4 default lights, Id think that would cause wash out, but yours ISNT, and thats very interesting...

I dont think through all of these tests, no one has mentioned "negative lights"... I suppose no point adding salt on the open wound, LOL!!! One step at a time :)

There are 3 kinds of people in the world. Those that can count, and those that can't..
