I've been working on Doctor Who regeneration effect at The Mill Film.
My job was to create the regeneration effect for the little girl and for the doctor.
-I've used Maya Particles, rendered with 50 passes of playblast.
You can find these sequences on:
Doctor Who S06E02 -Day of the Moon.
Doctor Who S06E02 -Day of the Moon.
Doctor Who S06E01 -The Impossible Astronaut.
