C4 is a Lightwave 7.5+ tool, designed to break up and explode closed volume objects. It consists of 2 plugins : "C4 : Destruct" is a Modeler plugin that randomly breaks up objects based on several user-adjustable parameters. "C4 : Detonate" is a Layout plugin, that handles the actual explosion (animation) of the broken-up object, based on dynamics calculations as well as extensive user control.

C4 can accurately calculate and use physical properties such as mass & centers of gravity for broken up objects, and use them to assist in a more realistic explosion simulation.
