I was Commissioned to make Trash and Trash bag for the game "The Shadows Lengthen" http://feral3d.com/
the Final mesh at only 200 Poly.
I used Particle system to generate a pile of garbage and made it tile-able.
each item had an ID to use in creating the material.
These are the individual maps generated for the garbage and trash bag.
these were the final maps created using the generated maps.
