Gosh, this will never be done. I still left 160 frames to render, which is about another 2 days. The whole animation really will take me more than one month to render. I finished all the 3d models for Sweep and Sweep Cut sections today. Beginning working on Loft and Freeform Section. It will become more and more complex, more and more interesting, and more and more challenging. Gook Luck!
