Map Builder Forge is a new mod for Grand Theft Auto V singleplayer mode that allows users to create maps directly within the game. The project features a create mode for placing models, vehicles, and peds anywhere in the map. The goal is to give creators an expanded way to build maps in GTA V.
Key Features:
Create mode for placing models, vehicles, and peds anywhere in the map.
Edit mode for flying around the map and selecting existing entities.
Save maps in (.ymap.xml) and (.json) formats.
Load maps directly from your (scripts/maps) folder.
Complete Keyboard/Mouse and Gamepad support. (Xbox Controller)
Additional Features:
Entity Properties menu for precise manual adjustments and advanced settings.
Speed modes for default, fast, and precision movements.
Dedicated movement and rotational modes for precise editing and flow.
Static/Dynamic toggling for all entities.
Vehicles snap to the ground surface / water naturally.
Entity Properties have free cam editing capabilities using hover selection.
Camera zoom using mouse, keyboard, or gamepad in all modes and the preview window.
Search filter for models, vehicles, and peds.
Ability to delete entities quickly in create mode, edit mode, or menu.
Dedicated reset entity rotation function for keyboard and gamepad.
Horizontal/Vertical individual movement functionality.
Increased debouncing delay to prevent issues due to occasional model incompatibility.
No set model placement limits by the script. (limited to built-in game limits)
Saving Maps:
Once you name and save your map in-game, go to your (scripts/maps) folder and locate your .ymap.xml save file. Start OpenIV in edit mode, then drag and drop your .ymap.xml file into OpenIV to convert it to a .ymap file. Converted maps are Singleplayer and FiveM compatible.
Save map in game (.ymap.xml or spooner .xml)
Drop into OpenIV (.ymap) / Menyoo to YMAP Converter tool (spooner .xml)
Map is now compatible with Singleplayer and FiveM.
