The idea was to have 2 people on the animation, one on FX and me on environments, textures/shaders, lighting, rendering and compositing.
I had to render(build,light and colors) 80 moving shots in 1 mounth and a half, so I didn't used a lot G.I, but lights with Vray Shadows to render faster.

Used Vray for 3dsmax and After Effects.
All FX were made in 3D by Julien Legay excepted volume lights, little particles in the air (atmosphere effect) and the girl transformation that I made in after effects.

Here you can see the final result (non mastered images)
(Compositing and lighting breakdown coming soon)
