That multiplier can't go over 0.01 to smaller number anyway, you can put 0.001 but no matter what you put, Vray still render image with mimimum value 0.01 for final result. Use scroller beside that value field, whenever you go down 0.01 next step it go to pure zero ~0 in number value. Some input fields in Vray don't allow extreme input value (different from each other, they're not same about input range). I’m not sure but for my eyes and my time playing vray in rendering.

I just lower the AA Max. subdivs 100 to 16 or 20 to avoid stucked buckets on high dynamic parts (since I don't need free float) http://www.spot3d.com/vray/help/150SP1/tutorials_unisettings.htm Thanks again !

I love the fine noise in the renderings. i assume that you used brute force as, at least, you primary gi engine. Would you mind posting your rendering setting? thanks in advance, Wayne fantastic renderings and an insight into this great vray setting which opens up all sort of possibilites.

Found it through the ChaosGroup forums. I'm actually doing a demo of VrayRT here in Chicago and, if you don't mind, I was going to use this as one of the test scenes. It really is one of those settings in Vray that is highly intimidating, but once you understand what does what you can get some amazing results. Heck, with some of those shots you could make some pretty amazing artwork! Great little test you did here. Found it through the ChaosGroup forums.

Maybe the light setup add more color in my renders (sun & sky actually) Thnaks for your comments,
