LW does not treat the various surface settings as seperate layers;
ie., Diffusion is not seperate from Surface, Transparency isn't sep-
erate from Diffusion, etc. Instead, they are treated as a hieracrchy,
Transparency being the highest (over-riding) priority. Thus, to ac-
complish what you're asking requires that you have an entire
second layer of polygons "hovering" over your base surface on to
which you'll put your transparency map.
You can do this by taking your base object into modeler and select
all the polys assigned to the surface in question. Copy them to an-
other layer and give them a different name, something relating to be-
ing a transparency, or so. Put your base model in the BG and select
a view that gives you the clearest side view of the copied polys and
model. SLIGHTLY move the copied polys out away from the center
of the model, even a millimeter will do (use the Numberic button). If
the copied polys surround the object, use the Size function and
Numeric to increase the poly's some fractional amount, say a factor
of 1.01 or so.
Save these polys as a new object and load it up along with the base
model. Now you can use your Tx map OVER your underlying Sur-
face map.
