Opacity and specular working together in a deferred decal

Hey guys!

This is happening in my blood decal and I really can’t figure out how to get around it.

The alpha is masking the blood with a slight feathering on the edges and is making these edges shine in certain light conditions.

Any ideas?

Is it a mask? If so try turning sRGB off on the Mask texture and see if that helps.
