Wenzheng Huang

About

Unreal Engine rendering/graphics engineer focused on VR (Meta Quest), with shipped production work including implementing modulated shadows in the UE Oculus branch and extending support to point/spot lights for "Marvel's Deadpool VR" (2025). Demonstrates strong engine-level profiling and optimization (Unreal Insights/RenderDoc) plus custom lighting/shader work, including improving capsule lighting math to eliminate specular artifacts and building tooling like texture pre-streaming and a level checker to enforce performance constraints.

Key Strengths

• Owned and shipped UE rendering features end-to-end (modulated shadows) for VR production
• Delivered major GPU savings by replacing CSM with modulated shadows (3ms to <1ms on VR)
• Deep engine-level debugging and modification of Unreal rendering/shadow pipeline
• Built maintainable engine tooling with documentation (texture pre-streaming system)
• Strong profiling-driven optimization across CPU and GPU using Unreal Insights and RenderDoc
• Reduced CPU frame time by removing redundant physics queries (~3ms)
• Optimized gameplay targeting logic by replacing raycasts with capsule intersections (700us to <500us)
• Advanced shader/lighting work: custom light component + shader permutations; improved capsule lighting math to reduce specular artifacts
• Cross-discipline workflow enablement (constraints + automated level checker to enforce lighting/perf rules)
