Cilia and Mucus
This is from the NIH-funded UGA Vet School Project that I helped work on in July of 2010. This is the mucus with the cilia, though the camera pass is not here. The mucus is from particles, and the cilia is fur. The render time on this was monstrous, so we eventually had to go in a different direction, but this worked well as a prototype.
Made with Maya and AfterEffects.
