Hi all,

This is probably something I am doing wrong. I created a black & white image for a jar label (just some black text and a border.) When I use it as a texture map in the color channel on a glass jar, the black portions become transparent and you can see what is in the jar through it. This is with the setting 'White is Invisable'.
If I change the jar texture to anything solid, it becomes black letters and you don't see the solid color through it.
I tried making another layer between the label and the jar that is solid black (same size as the label), but the black part of the label is still transparent. Help!

This is unusual. Could you post an image of your shader tree? It sounds like you put the map into the transparency channel. Strange. -Kix

could you use a really dark grey instead of black until you figure it out?

Kix, I thought I had aded it in the color channel. I am still trying to learn the shade tree editor. Mark

Bikermouse, I have tried dark blue, Grey and Brown, does not matter, still transparent, but thatnks for the suggestion. Mark

Hi Mark, One of Carrara's great strengths will also bite you like big dog: the ability of un-filled values in shader children (sub- set shaders) inheriting the settings of the parent shader. In your case, the rectangular texture map was inheriting the transparency settings of the reference shader. The solution is to create a 'new' multichannel shader and specify no transparency so you can override the parent shader. Mark
