Hi Mike,

for depth_maps I use a variable to change every finish ( e.g. finish {specular
dfac*0.3 roughness 0.0003 diffuse dfac*0.6 reflection {dfac*0.03, dfac*0.1}}.
For the "normal" render dfac is defined as 1 and for depthmaps or other
effectmaps dfac is 0.
Together with a white fog you get your depthmap.
