Hey Ivo great to see you here. (je kent me misschien beter onder de naam Marti van het nvidia forum),

The lighting in these images is done really simple. I only use an HDR image as environment lighting. No use of portal lights. They give me strange results but I am thinking of starting to use them again as I a want to shorten my render times. Some renders take 20 hours to render wich is insane.
In some occassions I also use a couple of area lights to light up dark spots in the render.

This weekend I hope I have some time to use my render setup for the scene you have provided at the nvidia forum. Then I can share that scene with you so you can see my exact settings.



This is my last render. I really like this one. The composition is not mine...I coppied it from an image I found online. Hope you guys and girls like it. Feedback is always welcome.
