Alright, so I've been working with these height maps and achieved good results from a simple colour-based topography map perspective. However, I still have trouble rendering the natural features into beveled height maps.

Has anyone tried turning these DEMs into raised satellite-style mountains that might be able to offer some advise? So far as I've seen, rendering river paths and erosion aren't particularly hard, but making a gradient map and accurate bevel and emboss settings is proving difficult.

Would someone with more experience on making DEMs into beveled terrain maps mind providing some enlightenment on the matter?
