Another scan from my trip to Tennessee. In fact this was the first object I ever scanned.
I used mesh room for the initial scan then used Zbrush to clean up the mesh and Maya for retopo. For material work I used Substance Painter for the most part. For the areas that didn't show up in the scan (such as the bottom and parts of the sides) I used Substance Designer and Alchemist to create a material that looked similar to the rock's surfaces and blended the materials together in Painter.
