Games Art Spring - Creating a Rock

To create a rock, I followed a useful tutorial I found on YouTube. The process starts by cutting sharp angles off of a cube in order to break up the uniformity of the cube and forming the general shape of the rock.

 

Then, using the Trim Adaptive brush and a square brush alpha, I trimmed the hard edges of the shape. Eventually, this process will begin to resemble erosion and weathering on the surface of the rock.

I also started adding small amounts of noise in order to make the detail more varied.
