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.Matthew Andrew Berge wrote: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, Andrew Matthew Hagerty wrote: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-- ¸.·´¯`·.´¯`·.¸¸.·´¯`·.¸><(((º> .¸¸.·´¯`·.¸><(((º>
