Build your map
Hey everyone 
I’m releasing ShellyMap, a standalone in-game YMAP editor for RedM. Place your props directly in the world, tweak everything live, and export a finished, ready-to-run resource in one click.
No framework. No database. No dependencies. And it’s free !

Ctrl + clickand edit the whole batch at once, the gizmo keeps your spacing and rotates the group around its center.
