Hi there!
I´d like to fade out the bump texture to the top of the glass (since condensation stops where the cold liquid inside ends). Is there a way to apply some sort of transparency map to define where are more or less drops?
Thank you dear Forum :)


You can drive through a fade texture and a color-to-number node the bump height. Or you can use the fade texture as a mask to clip the bump texture.
You will see this solution in the ice glass scene from the default scenes in the library.

Hope that helps.


P.S. written with a mobile device so I can't share an example scene
