having become obsolete with addition of GIVariables, development of gather node deprecated after poser 7, in which it reached its most elegant implementation.  currently no "aura" channel/node in poser, hence necessary to fake it using IDL, lite-emitting channel on glowing surface, and aura on partially transparent conforming (co-normal, shrink-wrap, edge-blend) surface, the latter of which can also serve by itself as glowing ghost/jellyfish if no aura needed.  some of these guys may have done some ghosts/xray pix using this already.
