Mario, Benedikt:
Thanks for resonding.
I did not quite explain my self adequately yesterday about the material
types (or maybe I did and I don't under stand myself)...So let me
try once more. I have several viewport (channels), 15 or more, all
viewing into one scene. Within this scene, I have several aircraft. Each
channel is assigned an aircraft as the "aircraft of interest" for that
channel. It is possible that 3-4 channels may be assigned the same
aircraf but viewed from a different perspectivet. Within each channel,
the "aircraft of intereset" for that channel is to be rendered exactly as it
should be; I would like all other aircraft within the same channel to be
rendered completely black. The intent here is to used the black aircraft to
stencil out portions of the aircraft of interest when appropriate.
Currently, I have node a draw traversals in which I try to use the stencil
plane to accomplish the same task. That has not yet yielded the result I
was looking for. I figured I could change the material type and/or turn off
the lighting for the aircraft which are not the "aircraft of interest" for that
channel in the node pre-draw and change it back to normal on the node
post draw . That also did not seem to work either.
I'm not completely sure how to use the Geostatetables, but my
understanding was that it was on a per channel basis only. In this
situation I need it on a node basis as well as a channel basis. So if your
previous suggestions are still the ones to persue, let me know.
Thanks again.
