3D Shell

The shell was modeled in Maya. ​Most barnacles are modeled in Maya. The top shader's base color is a picture of the shell that was altered and drawn on in Procreate. The same picture was used in black and white to connect to a bump map for the top.

 

The bottom shader is made up of two bump maps, that create the different types of lines on the bottom of the shell. The pictures for the lines were each drawn in Procreate. The specular color is connected to a facing ratio and ramp that create the iridescent effect on the bottom.
