- 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.
