I had the same question. Here is my answer to it. With some examples.

Is it possible to use a different objects to "normalize" gradient?

After fiddling around with the nodes, the answer to my original questions seems to be Yes. The key is the location of the center point of the reference object - here the rectangle. (Thx, @NP5 for the post) Center at z = 0 [image] Moving the center point in the rectangle down impacts the other objects. [image] Moving the center point up [image] Nodes - Object is the reference geometry. Use Object as vector node. [image] Hope this helps. Ray
