Developer toolset for making Mass Effect trilogy mods
ME3Explorer - ME3Tweaks Fork has a large set of tools to help you accomplish what you need.
The ME3Tweaks team has focused on fixing bugs that lead to frustrating debugging sessions when developing mods. We also focus on improving performance such as better redraw time, hardware acceleration, and fixing memory leaks.
The ME3Tweaks Fork of ME3Explorer has had multiple tools rewritten from the ground up that support much better scaling than the old tools did. This means your 4K monitor will actually be usable when you're using the toolset.
The ME3Tweaks Fork of ME3Explorer is the only actively developed version of ME3Explorer. Join the ME3Tweaks Discord to make your voice heard and influence the development of the toolset.
Package Editor is the main editor that developers use to edit the toolset.
The main editor tool for the series, Package Editor lets you modify textures, meshes, sound, properties, and more all within a single window, with the file shown in it's logical heirarchy.
With multiple subtools to get the job done, Package Editor is the premiere tool to use for modding.
In order to create mods, you need to typically edit existing content, and Asset Database is the best tool for quickly finding what you need.
In addition to Package Editor, ME3Explorer - ME3Tweaks Fork has multiple tools dedicated to specific workflows.
Modify kismet sequences to create your own flow of the game, from conversations to combat. The new version written for the ME3Tweaks Fork works with Kismet Logger for debugging and automatically can logically layout a sequence.
Edit pathfinding networks to allow movement from non-player characters. Move, add, or remove level objects to customize the world.
Modify conversations with easy with Dialogue Editor, including interrupts and charm/indidate requirements, FaceFX, and audio.
Listen to audio from all 3 games. Replace audio quickly and easily in Mass Effect 3 without having to use the Wwise authoring interface.
View and replace meshes for all three games with Meshplorer. You can even port (in limited cases) meshes from ME1 and ME2 to ME3.
We recommend a minimum of 8GB of RAM to run the toolset.
