Plastic shader with DGS

[hansn]

Sorry - I have no educated answer on that one but would like to add a question - isn't dgs obsulete since blinn can produce blurry reflections?

I thought MR materials were better than Maya’s, especially the Dielectric and DGS. Yes, I can achieve nice results with a simple Blinn material plus some blurry reflections, but I think the DGS material looks better and more realistic. The only thing I don’t like about it is that it isn't intuitive at all. I spend too much time changing parameters without a clue...

Physically more accurate, but better? I don't think anyone can defend that statement. The 'wood' look that you don't want is mainly caused by the glossy reflections, I think. Can't you just turn down the Shiny completely to get the hard plastic look?

from the look of the image you posted harder higlights would help it look more like hard plastic try increasing the shiny value in your DGS material. Higher shiny = more specular surface looks, lower shiny = more diffuse surface looks, shiny u&v used for anisotropic looks and shiny must be at 0 for these to work.

I think that thread is more about making maya shaders look and behave like DGS, very informative.

for more basic DGS info try http://www.highend3d.com/boards/index.php?showtopic=158994

Thanks zmip and tfritzsche. I’ll try what you suggest. I just rendered the whole scene with regular Blinns with a little of Blurry Reflections. It looks more like plastic now.
