shader help (metallic paper)

#1

Hi

I am trying to achieve a metallic paper for a label.

Applying bump maps and fiddling around with the reflection glossiness have not given me the desired results.

I am using V-ray for Maya and am confused with the lack of a specular attribute. So if I wanted to apply a noise map to the specularity of this material where would it go?

I’m guessing the reflection glossiness or highlight glossiness but I can’t get that metallic shine to it.

thanks for any help

Could you provide a reference photo of what you’re trying to achieve?

Your issue is probably that you don’t have anything interesting to reflect, if the kind of label you’re talking about is what I think it is, you’ll probably want some white and black stripes to make a reflection map, as though you were making chrome. Maybe something like this…

This may help too…

thanks for the suggestions, the problem with the shader was that I was trying to achieve two things with one shader.

I was trying to keep the metallic look without making it look like solid metal (its metallic paper), so I blended a metal coat material with a noisy opacity layer on it, and used the paper label texture as a base material. That plus a slight bump map gave it the two properties needed.

some example pics of what you got now (both shader setup and renders) would help.

Also include some example, target, reference pics if possible.
