I am using PP2012 and what I need is a clear glass material (for a bottle) that I can add a label to (plain text alpha map) and be able to make that text any color and/or a metallic.

I have a bottle and the liquid inside must show thru the glass (the liquid is a separate object and the bottle glass has thickness).

I've been trying all afternoon to knock the label out of the glass material with its own flat color and tried metallic too, but I keep bombing ;).

Any help would be appreciated :).

paper label or just lettering on the glass ?  you can mask it without much trouble. seperate shaders for the glass and the lettering before the node using the mask.

I think I have an example from a couple years ago.

I tried that first thing. LOL And no paper...just lettering.

Didn't work for me. Guess I'm gonna need an example.

Then it is a matter of adding a mask

This is the simplest way of doing it. Now you can modify the glass as you wish

See example

Math node is a simple substract to get the inverse 
Fresnel is the standard default fresnel
The texture node contains the movement of the lettering to get it into position

 I masked the transparency value and used a blender node on diffuse.

late for dinner , will post the nodes later if Bill doesnt.

Did that ;). But thanks. :)

Ok, I solved my dilema by creating a "label" material zone. Thanks guys.

Quote - something like this: you need inverted maps...one for the stuff you want to be reflective/refractive and one inverted version of that for the defused lettering/lable

I do have a mask and I did use it inverted, however - the glass mat I'm using uses the reflect, refract and the alt specular. Like I said above, I made a label material, made the stuff I didn't want transparent and I can do whatever I want with the letters. Problem solved ;). Won't work with some stuff, but in this case, it worked well.

The discriminator map should control transparency, reflection, refraction, and specular as well as the diffuse.

You know how to make a glass that goes into Alternate_Diffuse, right?

You know how to make a paper or paint or anything that goes into Alternate_Diffuse, right?

So - you have two shaders - glass and paper (or whatever) - each resulting in one node that goes into Alternate_Diffuse.

Combine them with a Blender node, and run your mask into the Blending factor. The Blender goes into Alternate_Diffuse.

PS - Because of Poser's internal refraction mistakes and/or deal with thin glass, I don't use the Fresnel node. To simulate thin glass, build it up from reflect+refract+fresnel_blend and use different IOR in the refract to get it to behave.

Thanks BB...I know how to make the alt diffuse things...just wasn't clear on how to combine them. I think I tried every way BUT the way you have it tho. LOL.

Brain dead today ;).
