How 138 Software Companies Powered Nezha 2’s Success

The director highlighted that the "power of teamwork" among 138 Chinese animation companies was the key to Nezha 2’s success. Compared with the first film, which involved 70 companies, 1,864 shots and 1,400 VFX shots, Nezha 2 increased to 138 companies, 2,427 shots (+30%) and 1,948 VFX shots (+40%). The production team repeatedly refined each effect to achieve the best result.

1. Animation pipeline tool development

Suzhou Hongjing Film Culture Co., Ltd : contributed a quarter of the whole‑process production, with a 160‑person team working 26 months; developed an automated asset‑management system for batch processing and version control, improving team collaboration.

Base Media : built a self‑developed VFX toolchain, took on high‑difficulty shots abandoned by foreign teams, and delivered dynamic particle effects and complex scene rendering optimizations.

Shenzhen Zeson Software Technology Co., Ltd : provided complex‑scene rendering efficiency optimizations, previously contributed to "The Wandering Earth 2", and specializes in physics‑engine development.

2. Effects and rendering technology

MOREVFX : created a large‑scale crowd animation tool that enabled 200 million characters to be rendered in the "Flood Battle" scene.

Shenzhen Lockte VFX Technology Co. : delivered the "Rift Claw" lava effect, using an eight‑layer fluid‑stacking technique and high‑difficulty particle tools.

Huaqiang Fantawild (Shenzhen) Film Co. : developed an automated waterfall simulation program, integrating 50 high‑performance workstations for batch water‑flow processing.

Shenzhen Kapu Creative Advertising Design Co. : contributed visual‑effects optimization through an automated texture‑generation tool.

3. Data management and collaboration platforms

Beijing Daqian Sunshine Digital Technology Co. : built an animation asset‑management system supporting multi‑team collaboration, version control, and distributed production workflows.

Chengdu Yunhaitianju Technology Co. : offered a cloud‑based animation asset sync system (AAMS) that improved resource reuse and management efficiency.

4. AI and automation tools

Suzhou FanshiJie Film Technology Co. : developed an AI material‑generation system that accelerated texture and lighting rendering.

Shenzhen Zeson Software Technology Co. : focused on physics‑engine and rendering optimizations for fluid‑interaction and chain dynamics; created an automated solver for high‑difficulty particle effects involving billions of particles.

Shenzhen Ruiyun Technology Co. : built a cloud rendering platform using distributed clusters and AI denoising, cutting a 3‑second scene render from 412 days to 24 hours and handling nebula effects with 5 billion particles.

Shenzhen Black House Creative Co. : developed hair and cloth simulation tools for character detail, reducing manual intervention through automation.

MOREVFX (again) : employed an AI‑assisted crowd tool in the "Flood Battle" scene to manage 200 million characters, using AI algorithms to optimise particle motion paths.

Beijing Daqian Sunshine Digital Technology Co. (again) : integrated AI‑driven task allocation and progress monitoring into its project‑management platform, shortening distributed‑team collaboration cycles.

Nanjing Xuguang Guanying Cultural Media Co. : created a render‑farm scheduling system that incorporates intelligent resource‑allocation algorithms.

These software tools, AI solutions, and collaborative platforms illustrate how modern technology underpins large‑scale animated film production, turning artistic vision into a technically achievable reality.
