Hello, I made a simple blueprint that reduces the opacity of a material if the player is standing in front, this worked fine but now that i’m implementing assets that already have materials I have arrived at a problem.  
These materials aren’t Translucent so the Opacity is not enabled. I was wondering what would be a workaround for this?

This is the blueprint that controls the opacity of the material.

Nvm, I found the solution by changing the mesh blend mode to Masked and then setting the scalar parameter —\> DitherTmportalAA —\> Opacity Mask.
