The opacity of translucent materials in a UMG retainer box cannot be changed on my machine. It seems to work for others though.

It only works when the material is set to additive or masked (with the output node connection changed in the screenshot ofcourse).

See an example here:

Hi all.

Meet same problem: when you change opacity in material it drops to 1 (for white color in texture).  
A temporal solution is to multiply texture on modified opacity.
