If you are interested in something like this I did this guy in the material room using no textures.  ( Only works for Poser 5 and 6)

1.  On PoserSurface:

Set Diffuse Color to black
Set Specular Color to Yellow and value to 1.000
Set Ambient Color to White and value to 1.500

2.  Attach Cloud node to Specular Color, Ambient Color, and Displacement.

Set Sky Color to orange
Set Cloud Color to black
Set Scale to  0.200
Set Complexity to 12.000

3.  Set Displacent to how lumpy you want the firgure.
I used 0.0484

4,  In your render setting make sure you have
Use Dispacement maps checked on and
set  Minimum Displacement bounds  to 1.000
