Depthbiasedalpha in the diffuse node

[Dralex789]

So I am plugging in the depth biased alpha expression into the diffuse part of my material, but when I do I get these stripped lines between black, and the other color I am using, as seen here



Does anyone know why this is caused? and what EXACTLY is outputted from the Depthbiasedalpha expression?

Nevermind I think I have it solved. It was the type of surface I had on it.
