I am trying to use a DEM for a bump map and have been having some issues. The DEM is a high resolution and looks to be fine, but when put into the bump map slot it becomes pixelated. Has anyone else run into this issue? It almost seems as though it's a mixture of contour lines and pixelation, but nothing is present on the image itself. I have attached two renders of the image. One is in the bump map slot and the other is in the diffuse slot, hopefully that will help explain the problem.
