This session demonstrates how, with advanced global illumination technologies as the foundation, and through close collaboration between art and technical teams — the team reimagines the classic browser game Roco Kingdom as a 64-square-kilometer open-world cross-platform experience. While retaining the original art style, developers leverage technological innovations to overcome key limitations in memory, bandwidth, and performance. This enables delivery of dynamic day-night lighting effects across multiple platforms and devices, while maintaining visual consistency as much as possible.

In addition, this presentation will focus on sharing the various technical challenges encountered during the implementation of global illumination in an open-world, cross-platform game — along with the team's corresponding solutions, strategies, and insights.

Takeaway

Learn how the R&D team upgraded a classic IP browser game into a 64-square-kilometer open-world cross-platform game using advanced engine and rendering technologies. This includes solving the challenges of time-of-day (TOD) global illumination through a hybrid precomputed-realtime solution; overcoming memory, bandwidth, and performance constraints via technical and art pipeline optimizations; and achieving seamless transitions between TOD and scene lighting, as well as consistent art quality across multiple platforms. These practical processes and experiences are highly valuable for game developers seeking to revitalize classic IPs.

Intended Audience

Targeted towards engine tool developers, technical artists, and other professionals with rendering backgrounds.
