First of all congratulations for your work. Its been an inspiration and a learning tool for me. I’ve been using GH for a year now and still considering my self as a newbee. I have a problem with your incident solar analema definition. While its seems to work fine, I don’t get the gradient result on the geometry surface. I only see a plain color (blue on this case). The surface that I use as an input is a simple Nurbs nothing fancy. And also the gradient component is orange as if its not receiving any information. I’m using the latest GH version 0.6.0059, perhaps thats the problem

Thank you very much

cheers
