Decal opacity mask not working - why?
I've also tried connecting alpha channel, red channel, etc. + changing opacity mask value, changing sampler type... - still not working. What's wrong with this material?
UPDATE: When spawned in world, opacity mask is working, but not properly - instead of "X" i have two parallel lines... Very similar problem to this: https://answers.unrealengine.com/questions/66356/decal-become-square-when-spawning.html
The problem is with your arrow facing for the decal. The decal is applied to a surface in the direction in which that blue arrow is facing. Here is exactly what I am talking about.
Properly Applied Decal
Improper Arrow Direction Decal
This should resolve your issue! :)
