Clean up / Restore / Misc. FX
Miscellaneous FX shots requiring particular treatment : glass broken after being hit by a fighter, logo change since it did not match the right company at that time, fighting details such as thinned out cotton from cut clothes and fliying and slicing hair of a hat, cable removal used by the set FX during fighting sequences.
Among those effects, the cut bamboo pole and the cut ribbons required more research and development than the others.
