설명
Lightweight Editor Performance Mode is an editor-only Unreal Engine plugin that lets you switch heavy editor scenes into a faster, lower-cost viewport state with one click.
Instead of manually changing scalability settings, rendering CVars, screen percentage, Lumen, shadows, fog, realtime viewport mode, and view modes every time a map becomes slow, you choose a profile and enable Lightweight Mode. When you are done, Disable Lightweight Mode restores the backed-up editor quality settings and viewport state as safely as possible.
The plugin is designed for large worlds, dense scenes, heavy lighting setups, cinematic maps, and asset-heavy environments where editor responsiveness matters during layout, placement, review, or iteration.
