Removal of standard roads/buildings and replacement with damaged, overgrown, and barricaded props (YMAPs) to create a post-apocalyptic feel. Fortified Safe Zones:

Do not cluster thousands of props in a single area. Space out your map edits. If a player’s PC has to render 500 custom props plus 30 moving zombies in one intersection, their game will crash. 2. Manifest Generation

Avoid importing models intended for offline cinematic rendering.

Utilize portal systems inside MLOs to prevent the game engine from rendering the outside world while a player is indoors.

Place makeshift graves, warning graffiti ("Don't Open, Dead Inside"), and scattered luggage near evacuation points. 3. Server Optimization and Performance Management
