Over a two-month period, contributed to LevelBuildingSpace and JoaBories/WS_Chair by developing and refining 3D environments using Unreal Engine, Unreal Engine Blueprint, and UnrealScript. Work included expanding corridor systems with new assets, improving geometry and visual fidelity, and resolving level map issues to support stable, iterative development. Enhanced asset libraries for room creation by integrating new meshes and materials, and advanced cinematic sequencing for scene assembly. Demonstrated proficiency in 3D asset integration, environment art, and level design, collaborating across design and engineering teams to deliver robust, reusable assets and workflows that accelerate environment production and support future feature growth.
