;Compute the distance from the vertex to the light   
dp4 r1.z, v0, c12     
 
;subtract the near plane distance from r1.z (the distance)
sub r1.z, r1.z, c4.x

;multiply the resulting distance by the scaling factor
mul r1.z, r1.z, c4.y

;Output the 8bit distance into the specular color (v1 in the pixel shader)
