I am building this for a demo video of the NeverMiss rat trap. I am building the trap in 3D Studio Max, and rendering in MetalRay. It is still in an early stage, but I wanted to track my progress.
These renders show the main mechanics of the trap, the loading cone is used to set the trap.
I am now working on the trap casing which is a very organic shape, so I am brushing up on my nurbs skillz.
