Cool! You're awesome

[@Waterboi505]

Why did you dot product the Normal map with the Camera position? Was it just to convert the normal map to a grayscale?
In this example will you see the most dramatic change if the camera teleports to the opposite side of the origin?

[@sherifmedhat7920]

i dont get it either .

[@athers102]

Is it possible to use this to have a texture always face the direction of the camera somehow?

[@williamlacrosse9389]
