You cannot gradient a NURBS surface in this way. You have to create a Mesh from the Surface in order to colour each vertex to create a gradient.

Thanks Danny. Is there also a way to bake colours as they appear?

Meshes will Bake with their assigned Vertex Colours, but any other object you need to use Giulio's BakeAttributes Component which you can download from Here: http://www.giuliopiacentino.com/grasshopper-tools/

I've changed the input surface into a series of meshes that I want to analyse. But when I try to create a surface from a grid of points, the error 'U count value is not valid for this amount of points' appears. The expression U+1 is not working...

the mesh should directly bake with the color info...no special baking required...to render you will need a renderer which supports per vertex shading. (luis fraguada)

but i have now used the "bakecolorattribute".

what should i do now?

danny, do you know an example how to proceed?
