Cycles Alpha Mapping - New problem to me

I’m currently working on a guitar amp and want the label to put a plane, using UV mapping.

I proceed as usual and use the nodes to get the texture transparent.
Behind the object a bright surface appears … why?

Can someone help me?


Here is a setup that worked for me. It looks almost identical to yours. I assume you have verified that your alpha channel is fully white and black?

PS: I notice your amp does not go up to 11.:slight_smile:


Thx for the quick answere!

Yes my alpha picture is completely black/white as you can see in the .blend file
