Hey, everyone!
I've been (re)-investigating the question of using realtime renderers to create animated movies in 2016, given the existence of fast GPU conventional rendering techniques.
I know we've got some serious experts here in this field, so I'd be really interested in thoughts and comments.
My initial tests and experiments are written up over at

Very interested to hear if anyone has suggestions of other pipelines, other engines to try, or ways to solve the problems I found!
