Hi, can’t seem to google this one but in scene, game, and build this texture will not show unless I’m fairly close. Changing from Transparent diffuse shader to a non transparent shader works but I want the transparent one. Anyone know why it’s working this way? 
Found out this has to do with two transparent shaders in use on top of each other such as on the ground and on a decal over the ground. I simply copied the transparent shader and added 10 to the renderque and put it on my decal to fix it.
In the case that you are still looking for an alternative solution, you can download my Decal System for free. It contains some shaders that solve exactly that issue.
