Thanks for the info. Unfortunately my exp. level is not high enough to
put to use what you described without an example or two.
I did come up with another idea about how to do this, I just need one
piece of information: It is possible to have an object report a piece of
information to a material? For example, if I had 28 objects and used a
tag to hold an "id" 1 to 28, is there anyway to pass that number to a
material? That way I could use a simple calculation in the material to
derive the color or illumination of that object and I would have much
better control over the fad I'm looking for. Also, this works out
because the corners of the wall will happen in non-consistent places, so
having 28 pieces to the wall would actually be easier to work with.

Hi,
As usual there are a few ways to achieve this result, I think you
will need to use a mesh object to do it easiest, you could say use an
SDS object with either set to polygonal interpolation or with extra
curves near the edges to achieve the sharpness u need, then use point
based scope by adding a custom channel and applying it to the points
you want then it will automatically blend for you between points.
Otherwise you could use UV mapping and use a vsl shader with a scope
or color etc UV based fade.
I am not sure of you experience level, so if y need some more help, I
will give you some more details.
rgds,

Greetings,
I need a material that will fade a color (or modify illumination)
over the length of an object. Think of a wall, on the left I'd like
white, on the right some color, with a nice even fade across the
surface. That much I figured out. What I'm having a problem with is
when I need one or more corners in the wall, I can't figure out how
to start at one end and follow the wall's "path" to the other end
while fading the color.
Currently my wall is an analytic polyhedron, but it could be a mesh
too, as long as it has sharp corners. My current material works fine
as long as the wall is straight, but I really need the linear fading
to continue around the wall's corners.
I'm hoping someone can give me some ideas on how to do this, I'm at a
total loss.
Thanks,
Matthew
