I noticed that when I was texture bombing a material I was making that there were bright and dark patches presenting on the material. When I tiled it up to a factor of 500 I could see a clear pattern as you can see in the attached picture. I narrowed it down to coming from the normal output from Texture_Bombing. When I set the Is Normalmap (B) value to False, this went away. What is up with this pattern? Am I missing anything if I tell the Texture_Bombing node that my Normalmap is not a Normalmap? It seems to be working well in that state. Thank you for your time.
