Upin & Ipin Go Global: Crafting an Open World UE5 Game from Southeast Asia | Unreal Fest Bali 2025

Launching this year, ‘Upin & Ipin Universe’ is an ambitious open world game built in Unreal Engine 5, targeting PS5, PS4, PC, and Nintendo Switch. As the first regional IP developed by Malaysians to go global, this title represents a major milestone in Southeast Asian game development.

Shipping an open world game across multiple platforms comes with unique challenges. This session recorded at Unreal Fest Bali breaks down how Streamline Studios structured their memory profiling and asset streaming pipeline to ensure smooth performance across all hardware, from next-gen consoles to the Switch.

Watch Stefan Marcus Baier (EP) and Renier Banninga (Creative Director) of Streamline Studios, with their combined 20+ years of Unreal Engine expertise, share their insights on how to scale an ambitious project, optimize UE5’s systems, and successfully deliver a multi-SKU game at a global scale.

The session dives deep into how they leveraged UE5’s Lyra framework and the Gameplay Ability System to enable rapid design pivots based on player feedback, and also explores cross-platform performance optimization, focusing on World Partition, LOD/HLOD workflows, asset virtualization, and fallback strategies for lower-end hardware.
