With this asset I begun in ZBrush creating several rocks which I then placed on to a plane that was shaped like a pile of dirty and small rocks.


Next I exported the High poly sculpt into Topogun to create a low poly cage. Afterwards the cage was then sent to Maya to create a UV map and was the re imported into Topogun to transfer the data from the high poly to the low poly mesh.


Finally the low poly mesh was imported into the Unity game engine 4 where I used the standard shader with a difuse (albedo), normal, and ambient occlusion maps.
