I think it would be helpful to be able to display elevation contours on the triangle mesh, especially for animations. I ran into a situation where the altitude color rendering was so smooth you couldn’t really determine the shape of the slope. Being able to display contour lines would help this.
Currently you can change the texture color of the mesh to display the elevation (select Altitude (Red, Green, Blue)). Depending on the altitude of the mesh triangles, they will have different from blue to red. More information here:
However it does not give you many options to adjust the colors. Displaying the contour lines could help to better visualize the elevation on the mesh. We will pass your suggestion to our product management team so that they can study your suggestion for a future release.
