I have some curves that I want to render in Cycles; these are not blender curves, instead they are composed of a set of vertices, each having a color, and edges (but no faces).
Using the skin modifier, the generated geometry is exactly what I want, but the vertex colors are not propagated to the skin surface...
As an example (using Meshlab), at the left is what I want, at the right is what I have. Note that I can have colors way more varied than what is shown here.
How can I keep the vertex colors in the skin modifier ?
If this is not possible, then how can I render curves with colors in Cycles ?
