This is an very interesting little rock I found in my mother in law’s garden. The finer detail of the rock did not come though as it had a lot of detail. The end result with the texture map as an dump/displace map worked nice to give the rock the detail it lost during the decimation process.
Below is some other screen shots of the rock. Is shots the rock with texture and with no texture. Also a normal map view to show the model’s shape a bit better.
