I want to color a mesh with a slightly transparent colorgradient from red to blue based on the z-value of the faces/points. I found a Grasshopper script that does the job here: Grasshopper gradient color
Unfortunately even though you can change the transparency in Grasshopper - Rhino does not take that transparency into account. Is there a possibility to do the job without Grasshopper only with rhino? Or is there a possibility to do the job with grasshopper? This seems to be a known problem by the Grasshopper-Rhino community. Thanks for any advice!
Vertex colours do not support transparency. That will require a far more complicated approach of using texture mapping and a bitmap gradient as far as I know.
EDIT: works fine in Rhino6. Are you doing this in Rhino5?
yes I am doing this in Rhino 5. I will have to update to rhino 6 then…
Thanks a lot!
