I downloaded the nVidia normal photoshop plugin.
It is supposed to take a color image and make a normal map out of it.
I tried one of my textures and I am attaching it.
I open Blender 2.48 and delete the default cube and add a plane.
I create a new material and add the normal map as a texture image.
I leave the plane as flat orco mapped.
I enable the normal button and make sure it is set to tangent space.
I also change the map to tab so it is using Nor instead of Col.
This produces nothing. Why doesn’t my normal map work?
