Surface edge material?

[Builtdown]

Hi,

If I have only one polygon (ie. round polygon), how do I make with Material Mixer so that polygon edges are different material than the center of the polygon?


(I want to "blend" between two materials but dont know how...)

I have two polygons, pink and blue. I want to blend those together by adding some blue gradient on the edge of the pink material.
Is there some way to do that?

(My actual need is to blend a grass field material to a sand pathway).

This is actually a better pic of what I´m looking help for: So I have a model that has two materias (asphalt & grass). I would want to add sand to the edges where asphalt and grass meet. (So that sand blends to grass and blends to asphalt too.) How can I do that? Thanks!

hummm... I guess you have 2 different surfaces. I don't know any way to bend 2 different surfaces, the only thing I could think is to overlap a little the polygons (but not in the same position, one must be a couple of millimeters more high on Z), so you set an UV (omg!) and a gradient in the opacity. It isn't so fast to do and the result could not look so good.
