Hello everyone,
I'm trying to put a Logo on a bottle. For the Bottleglas I used miaMaterialx with solid Glas Preset.
I planar map the Faces for the Logo and assigned the same Matrial to those Faces therefore I have the same Matrial twice.

But the Logo has a not square shape so I can't fit into layout.I tried to make a Colormap and put it into the Refraction-->Transparency Channel of the MiaMaterial, but nothing happend. This is the Logo.

I want it like this without those black faces ( the blue marked faces should be glass):

You need to conect it to the cutout opacity of the mia material. Hang on i did a video on this some time back.

EDIT

Found it

Hi David and thanks for that video.
How can I make a Transparent Texture? I've tried it in Photoshop with adding a new Layer to the Background Layer and then cut out the backgrounds layer background and merged the two together. Taken this Texture to Maya it was not Transparent,the Background was there. I saved as a Tiff.
Do I have to create an alpha Channel? How do I make this?

you need to create an alpha channel. In photoshop cut out the image then select it. Then go to the channels tab and click save selection as channel this new channel will be the alpha channel.

If you can't get it let me know i'll record a quid video.

Iknow managed to cut out the logo through alpha on the surface.But because of alpha's 0 Information this area is colorless and thus does not fit to the rest of bottles material. what can i do to correct that?

I'd recommend you use the mia_material_x, there is even a preset for glass. I think the dielectric shader has outlived it usefulness, you can get rid of the grain but you'll have to use such high sampling that the render time will make you rip your hair out.
