During January 2025, Sol Kim focused on stabilizing box extent rendering and collision in the RETURN_XENIA repository. Addressing a critical bug, Sol updated the Unreal Engine project solution file, editor settings, and asset configurations to ensure accurate box component behavior and asset browsing paths. This targeted fix, implemented using C++, Blueprints, and UnrealScript, resolved discrepancies that could have affected gameplay accuracy and physics interactions. The work demonstrated careful attention to Unreal Engine’s configuration and asset pipeline, resulting in a single, well-scoped commit that improved both visual and collision stability without introducing new features, reflecting a precise engineering approach.
