Advanced Map Preloader for RPG Maker MZ

A modular, performance-focused plugin for RPG Maker MZ that enables seamless map transitions with customizable loading screens. 

Advanced Map Preloader streamlines player transfers by preloading destination maps in the background, eliminating lag and visual stutter. Ideal for large or complex maps, it uses a temporary “safe map” and loading scene to keep transitions smooth and secure. Developers can display custom images or fallback text during loading, and the plugin intelligently caches map data to avoid unnecessary reloads. Every feature is parameterized for easy integration into commercial or jam-scale projects.
