Clément Espeut developed and maintained core editor and asset management features for the HeapsIO/hide repository, focusing on improving workflow reliability, UI responsiveness, and performance at scale. He engineered robust prefab and scene management systems, enhanced the file browser with advanced thumbnail and texture handling, and delivered animation and shader graph tooling to accelerate content creation. Using Haxe, JavaScript, and CSS, Clément refactored complex UI components, optimized drag-and-drop and virtual list behaviors, and implemented caching and error handling strategies. His work demonstrated depth in cross-module integration, resulting in a more stable, maintainable editor that supports faster iteration and safer asset pipelines.

February 2026 (2026-02): Delivered core UI and editor enhancements for HeapsIO/hide, driving editor stability, performance, and usability. Key features include Virtual List Component Enhancements (scroll enum, smoother scrolling, improved item positioning and rendering, and auto-scroll; with font/layout correctness), Prefab Management Robustness and Shared Editor Context (refactored prefab hierarchy, lazy-child handling, removal of unsafe parent setter, ensuring safe parenting and editor context persistence), and Tree UI Enhancements (new tree structure component, styling system, and keyboard navigation). Critical fixes across the editor improved reliability: Scene Editor UX Fixes (root visibility during load, gizmo position regression, and improved undo/refresh/selection flow) and FX Editor Visibility/Lock Path Fix (correct path references to prevent wrong state persistence). These changes collectively improve editor stability, reduce manual debugging time, and accelerate content iteration for customers by delivering more predictable UI behavior and safer editing workflows.
