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?
What you need to do is change your ‘Decal Blend Mode’ to ‘Masked’ instead of ‘Translucent’, and plug your masked texture sample into the ‘Opacity Mask’ pin slot.
Hopefully this resolves your issue, but if you are still not able to get your material to function properly, let me know and we can further investigate.
No worries that was my mistake. I set up my own decal material using the ‘Emissive’ Decal Blend Mode and was able to get the opacity mask through a Linear Interpolation. Use the images below as a reference on how to set up your own material.
I’ve tried putting other textures to be sure that’s not a problem with this particular “X” texture.
EDIT: I’ve changed back to Surface, then changed Blend Mode from Masked to Opaque. Then changed back to Deferred Decal - now it’s exacly the same as in your screenshot, but it’s still deformed.
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.
