hello
i want add label to a bottle but in studio the texture applied to face and back (mirrored) of the bottle
i asked maxwell team in facebook since months and they says that they will make tutorial how to add label but they didn't make it

It's very easy. You need to leave your bottle geometry alone and offset a label geometry on it. Then, materialize both sides with label front and back. Just like in the real thing...

thanks Tom
bottle have thikness; how that work ?

Yes, the bottle has thickness. Just leave it alone. Make a separate label geometry which has no thickness.

thanks Tom
i make one material with two layers : glass + label (text and alpha )
than i make backface material : glass + label ( white material)
i use the same cylindrical mapping
----
can you show it step by step

I want to help you my friend;
I am C4D user and a few days ago I was rendered this image with Maxwell;



here is my setup about texturing, I hope to give you some ideas;





I hope I can help.

Nice render
thank you for your help
you make geometry as label ? or use layer
what i need is label with two sideds one for the logo the second blanc like in reality
i see image like that in maxwell documetation and i try tips of Tom but i don't sucsses : i am sure somthing is missing

I was modelled bottle and split front face of bottle for label.
My label is layered TIFF image (transparent background)..also I was used same image for alpha channel.
Which application do you use for modelling ?

thank you
why you split the bottle ? you can use cylindrical uvset and add layer to the material to apply label
i use rhino than modify texturing in maxwell studio

Because in real world, the label itself is an additional entity. It's not the part of glass body in physical terms. FWIW, you can still do it on glass geometry using the UV mapping and assign a combo material as you're attempting to but, this is going to be very complicated. Because for keeping the internal reflections correct, you should also place an additive mirror layer simulating the glass surface to the backface of your label. This is why I suggested the easiest and shortest way of doing it.

Yes like you said but I am beginner in Maxwell Render,I am still learning
Very different from C4D material system...a bit confused now ...for me..
Thanks for the tip,I will try this

we are all beginners ; no one know everything

Thanks Dear seghier,I will try this

Do it like this...

thank you feynman
i was wrong at the first time ; i thinked we can create labels like in keyshot with backface material
tom explain how modeling label than apply materials
in your example we don't need thickness with backface material feature
