I am using a merchant bought character texture that I wanted to try and add a little more life to it by adding some more bump to try and give the skin a pore like look.

So all I did was run the image file for the bump map in PS and added Noise at 15% Distribution is set at Gaussian.

That was it, just to see how that looks. I reloaded textures and rendered. Now I am getting what looks like the figure mesh showing through the texture. IF I remove the noise, you don't see the mesh. So what is making the mesh show through?
