You will get a super detailed surface without any bump map, only need a albedo texture.
Take a look at the screenshot image.It's a sphere model with the earth texture.We haven't bump map of the earth, so we cannot get the detail of the earth surface. You can try to generate bump map by CrazyBump, it's unsatisfactory.
That's why we need SuperDetailShader. You can get many details without bump map, only need a albedo texture. And you can customize fake bump texture if albedo bump is not satisfactory.
The video will give you a more intuitive experience.
