On this project, I designed and helped implement a system for creature genetics to enable a robust breeding and animal husbandry mechanic in game.

On any given animal, the mesh is comprised of many swappable parts that share a single rig, a grayscale diffuse texture, three colors applied via mask channels, and a pattern overlay, all of which are compressed into an atlas at runtime. The system extends to support patterns (spots, zebra stripes) that are shared across all animals of a similar type, i.e. quadrupeds, birds, so forth, and allows parents to pass on their 'genetic values' to their offspring. 

This same system was used to allow the player to customize their character's appearance and costume, with no change to the art pipeline, and all humanoid creatures shared a rig as well. I created and handled almost every 3D asset in the game. 

Some of the images below are a bit hard to decipher on their own, and are meant as examples of the versatility of this system. Rigs were shared extensively between animals in similar size categories.
