o.k., thx fr excellent tutorial, luke. in poser, default displacement causes the renderer to shift the apparent position of the posersurface in the positive normal direction (out), depending on displacement value.  two questions:

• what is yer avatar?  it reminds me of the lion from "wizard of oz"
• is it too late to add a page on the node needed to make displacement shift the posersurface both in-n-out?
