Metin2 NPC Outline Glow System (WoW Style Hover Effect) | C++ NPC Highlight Feature

NPC Outline Glow System (World of Warcraft style) adds a modern visual hover effect to Metin2 NPCs, enhancing user interface clarity and interaction quality. This system applies a smooth outline glow around NPC models only when the player moves the mouse cursor over them, similar to the WoW targeting and highlight mechanic.

The feature is designed for client-side rendering optimization and does not affect server performance. It improves player experience by making NPC interaction more intuitive, especially in crowded maps and high-population areas. The glow effect is fully configurable and can be adjusted in intensity, color, and rendering behavior depending on server design needs.

Compatible with modern Metin2 client systems and custom source builds, this feature brings a polished and professional MMO UI experience to PvP and PvM servers.
