A 3D model of Marya Morevna’s katana was created for scene 24 of demo storyboard. Download original model: katana.blend. License: Creative Commons Attribution 3.0.
Here’s layout of helicopter. The model is not completely tuned, but it already could be used. Other stuff could be fixed during the animation process. Helicopter state is controlled by IPO drivers. Watch it in action: ipo-drivers-demo.ogg.
