Hi @sibe​, the CONSTANT Interpolation Method takes z values into account; it draws on the z value of the closest vertex in the underlying model. Feel free to take a look at the SurfaceDraper's documentation for more. I hope this helps!

How is the closest vertex determined? Based on X, Y or X, Y, Z?

Hi @sibe​, the closest vertex is determined via X, Y only. Hope this helps!
