The Axis Animation team had access to 3D 'sketches' done by the Weta Workshop team. Using these, the Axis creative team started writing up short synopses for possible routes. The result was voicing the trailer from a single point of view, but not revealing the storyteller until the end.
Grey Goo Game Trailer
Axis Animation created all environments and human characters from scratch. Weta Workshop provided early 3D sketches as a starting point. The focus of the cutscenes were very much on the characters, this is where Axis put most of their 3D effort. Axis Animation followed their standard lighting and rendering workflow which includes Side Effects Houdini and its renderer Mantra.
The final trailer uses assets from cutscenes. All of the animation, environments and FX work are completely unique. Everything was brought together in Blackmagic Design's Fusion compositing software.
