OP has P6 IIRC, hence procedure in his case would be to load default scene (lites, figure et al.), replace it with the male figure that comes with poser 6, use front camera if desired, load a depth cue "prop" in matl room, then use att img settings for depth cue color. YMMV

p.s.: to use this as displ map in poser, convert to 16-bit tiff.  black (0) = 0displ, grey (0.5) = 0.5, white (1) = 1displ.
