Driven by the urgent demand for high-fidelity,low-latency,and reusable digital assets in virtual production,and addressing the inherent limitations of traditional modeling approaches regarding production efficiency and cross-platform in-teroperability,this paper presents a systematic digital asset production and management pipeline.With Shanghai Film Pro-duction(SFP)serving as the operational entity and its SFG Haopu Smart Industry Community as the engineering practice platform,the pipeline employs 3D Gaussian Splatting(3DGS)as the core modeling solution and adopts OpenUSD as the standardized asset format.Specifically,this study analyzes the design of multi-source capture workflows,parameter optimi-zation strategies for 3DGS modeling,the architecture of the OpenUSD-based asset management platform,and AI-driven asset retrieval mechanisms.Furthermore,it validates the feasibility of the"create once,reuse across multiple projects"strategy.The results demonstrate that while ensuring high-fidelity rendering quality,the proposed pipeline can significantly shorten the asset production cycles and enhances cross-project reusability.This work offers a replicable practical path for the localization and standardization of digital assets in domestic virtual production.
