The shaders in the video looks like the standard ones (wall_spec_ill and floor_spec_ill.) They produce specular reflection only, but with a good specular map, you can achieve really good results.
So, contrary to what Northern seems to be claiming, you can achieve results such as the ones in the video. There's also another segment shader (pixel shader 3 as opposed to the standard ps 2 one included with the most recent FPSC updates) made by bond1, that supports both normal maps and specular maps.
Whichever result you want to achieve, you will need the respective texture maps required for them to work properly.
