Produced from a vector displacement .exr created in zbrush. I used the process outlined by j meyer in the discussion thread. I found that for a good detailed result you need to set subdivs as high as your machine can handle. I also set uv maps to max 8192 x 8192 which may not be needed I have more experiments to do on that.
