A really quick update :

Cassie's scenes are fully written and rendered.
Eve's scenes are written, the first and shortest scene is rendered.
The render included in this post is from Eve's second scene.
Quality is good but it took me 3 hours to render. It's obviously too much when you're planning to produce 30 to 40 renders in the same light setting.
I'm going to run a couple more test renders to find a good compromise between quality and decent rendering time.

I'm going back to work.

Godspeed!
