see above for poser toon chader (wacro) with edge-blend lines. the main differences between edge-blend lines and poser toon outlines:

• toon outline puts a jagged line around the outside of the figure or cloth item, which causes oddities like finger bloat (bad)
• toon outline can't do interior contour lines
• toon outline can't do variable line widths in same render

if one just wants a black-n-white image, then skip the toon wacro step. reset all mtls to white with D3D script (or similar), apply edge-blend node to ambient value, render with no lites. I daresay they will have this more formalised and user-friendly in the upcoming P8 beta.
