Creating environments for my character animations is NOT my favorite thing in the whole world. I tend to get a little too realistic with them. Case in point, Nikki's Nightclub. Everything in here is either reflective, refractive, or gives off some kind of light. It's a nightmare for someone who's got just their one lowly little processor. If I remember correctly, rendering the backdrop for the Nikki character animation sequences took approximately one full day. And it was just single still. I'm still happy with it, however.
