The first assignment in the digital materials course was to create 3 different shaders: a 2D ramp, 3D material, and a form of bump or displacement. For my scene I created an underwater environment and used bump and displacement as well as a mix of 3D materials to create the sand and rocks. Multiple 3D materials were layered to create a complex shader. The seaweed and snail shell were created using the 2D ramp shader and adding multiple ramp layers as well as divisions to the shader
