A roaring 40! I love this plane (Curtiss P40 Kittyhawk) and thanks to some awesome blueprints found on the internet, I got the opportunity to model it in 3D! I used an interesting technique for the spinning prop blade. It was created using simple geometry and weightmaps used to create a transparent gradient to simulate the blur you see - Its a little trick of the trade that saved me having to use motion blur, or create a texture map to create the same effect.
