Please I need help with this material. I love Vray and I believe that there is somebody who knows where is problem. In my image is my horrible pictures with settings and bellow is what I need. Thanks..

Your material is actually nice. I would work on the environment and lighting. The photographer probably spent some time getting the lighting and reflections to work.

Probably no hard, point lights just soft, area lights.

[natty]

have you tried vray mats.. ?

re

I thing that my material is´t too good , Have you some idea how to perfect lighting scenes? Realistic shadows and of course coustic. I have a problems With details on car. Thanks

Add a falloff map in your self illumination and or reflectivity.. I'd suggest starting with a mostly black -> black perp/parallell setting to start with, and adjust the 'paralell' color from there to suit.

Good luck, almost there

Well it looks like you're using just one light. I would suggest starting with all VRay area rectangles. One light from the upper front (Key Light), one from directly on top (Rim Light) one from the side opposing the Key light (Fill Light). After you get this setup you can move the Side and Rim slightly forward and backwards and the Key slightly up and down. This is just an educated guess and you might not get exactly what you're looking for but it's a start.

I guess I just glanced at it the first time but after looking at your material again I see you're using Oren-Nayar-Blinn. This isn't a good idea with VRay and doesn't really lend itself to glass. You should also have VRayMap in the Reflection slot with a Fresnel Falloff in the Filter color slot. But like Natty mentioned, I think a VRay material would work much better.

re

Thanks a lot boys. The Oren-Nayar-Blinn material is mistake I know. Please Could you tell me something about shadows? As J_BUG write about lights, May I use shadows in all lights? Or only with fill lights. Thanks.

[natty]

try using an hdri to light and reflect in your scene... and a vray light set to not store with IIR map

re

Thanks everybody.There is my results.Thanks

[J_Bug]

Looks much better.
So what was your final technique?

Do you have your environment color set to black? Are you using any environment overide?

--Jon

[natty]

yeah much better

[pengo]

I think

I think that the backside of the model inside the glass should be visible a little

try with double sided too and maybe u could play with the filter effect in the extended parameters (standard material) like add

bye
