Bad alpha channel

Hi guys!
Tell me please, like everything was right. The texture labels and texture with alpha. All the alpha channel is present, but it still shows the surface ... Can not do right?

I think you have to tell Mental Ray that the bottle is everywhere transparent except for the label, thus plugging the alpha into Transparency, not in the diffuseTransparency... But I'm not sure I've understood the connection you did in the hypergraph

No, no. I have a label separately. TGA file format with alpha.
How to make it disappear, I do not know.
Nothing is working.

You should connect your inverted alpha map into the cutout opacity.

Thanks, but no effect

Do you mind sharing your scene so I can have a quick look? PM me if you don't want to give it to everybody.

As Chafouin said, being able to get a hold of your scene would be best. It seems odd that your cutout isnt working. Are you sure that the white/black of your alpha are true 100% white and black?
