They call this place Ft. Dobie, though no one knows quite what these structures were originally.
But when Spring is here everyone has to make the Pilgrimage.
Funny dark speckled patterns on the walls in the foreground came about from a mistake. Somehow I made a typo on the patch size in Compute Terrain. It became set to zero.
I wondered why the render went from 6 hours to 17 hours ! I can't recommend zero patch size, but it does give a different result.
