Re: Shading the edges of a Spline Object? 2004-02-23 - By joe_ashear

Technically you can make the outline without a texture map, but it's
probably not worth the effort. You can do this:
In the spline modeler, give the sign a very tiny extrusion, and use
the extrusion envelope to make the extruded end smaller than the
starting end. This will give you an object which has an outline built
into it.
Then create a Layers List shader in which color is applied to "front
face 1" and the other color is applied to the other shading domains.
If you're not familiar with shading domains and layer lists, it's not
worth learning about them just for this - it's a hacky solution anyway.
