설명
This system applies a solid fill color and an outer outline to 3D models.
When a model is occluded by walls or platforms, only the visible portions are highlighted, preventing outlines from appearing through the obstructing geometry.
Users can customize fill transparency, outline thickness, and the two color layers; styles can be set individually for multiple targets, all with low performance overhead.
Common use cases include character selection, enemy marking, interactive object highlighting, and object filtering in editors.
