UE4 Opacity map not working properly

Nick_Medukha · Feb 2019

Hey everyone,

I have a trouble with UE4 material setup:

Model is simple medicine bottle, it has 3 materials - pills inside, bottle cap, and actual bottle that needs to be semi-transparent with non-transparent label.

Cap and pills are fine, but actual bottle has problems:

Here are some settings & opacity map

What am I doing wrong?

You could have a separated mesh part with opaque material on the label. Probably this is the easiest way to fix it. You are not doing anything wrong though, this is a transparency sorting issue. Other than the opaque material, you could try setting sorting priorities, but the first solution would work much better.
