Sand, Sand Everywhere...

Sand dunes are a real pain in the ass to model convincingly... they are very distinctive looking, and quite tricky to texture... I initially just put a few bumps and dips into a subdivided plain and while it was fine for just getting an idea of scale and motion, they really doesn't look like "real" sand dunes...

So I have tried a different approach - this time using a greyscale height map that I drew using an aerial photo of sand dune formations in the Namib Desert...

As you can see it looks a bit more convincing (The dunes in the back are still the original "bumps") ... still not quite there and I suspect I am going to have to hand model some "Hero" dunes for close up work as these dunes do not hold up under close scrutiny.
