Alpha Map not working in Material

Hello,

I am texturing a scene and for some reason my alpha map does not seem to work, and I can't seem to figure out why. Even though I uploaded the texture, the map still remains at full opacity as seen in the screenshot below.
Does anybody know what could cause the issue here?

Thanks,
Luca

Uncheck "Image Alpha" and see if that fixes it for you. I can't see anything else that would cause the issue.
My guess is you are exporting an 8 bit PNG which does contain an alpha channel that is completely opaque.
Switching "Image Alpha" off will cause it to apply the mask based on luminance....or you can try exporting the png as 16 bit instead.
