I just ran in to a weird issue, never had before. I created a normal box with just a texture with normal map. when I put a point light above the floor it generated some ugly shadow, i have no idea how to solve it. I’m guessing its something with the normal map. when I remove the normal map from the material it’s working fine.
Solved it. Looks like the saturation was turned up for some reason, I have no idea how this had happend… well, it’s solved now. Now we all know that you should not pump up the saturation on normals map texture.
