As one of China's most significant examples of industrial-scale filmmaking, The Battle at Lake Changjin II demanded both absolute authenticity and exceptional production efficiency in its large-scale battle sequences.

CHINGMU provided an optical motion capture system for the project, capturing and digitizing the movements of actor groups to drive CG soldier characters, enabling the digital reconstruction of large-scale combat scenarios.

The production workflow included:

• Standardized capture of individual soldier movements (running, prone positioning, firing)

• Construction of a reusable motion asset library

• Expansion and combination via crowd simulation systems

Motion capture data was also applied to fine-grained authenticity — including impact response, movement inertia, and crowd rhythm variation — making the battlefield sequences more compelling and believable.
