I have to say, whilst I have experimented a bit so far with "no lights" and just a specular... I've generally still been "cheating" and using some Poser spots. Last couple of gallery posts I did for example... although a lot of the light is from IDL emitters, ramped up to 7 or so in their ambient channel. I'm just picking out highlights I guess with the spots... everything I'm doing is now envsphere enclosed, with an HDR (or near HDR) sky now... even when the light from that is only entering the scene indirectly, i.e. through a window, etc (even an off-camera window).

Last scene I did had a total of 8 envspheres in it. But that's another issue. LOL ;-)

Those morphable prop emitters look very interesting BB.

I'm also following the thread Anthanasius started and which was subsequently elevated to a whole 'nother level by BB, about "Lights and watts"... in case there's more to come there??

cheers ;-)
