Legendary Explorer 6.4

It's been about a year since our last stable release of Legendary Explorer, and we've made a lot of improvements! Hopefully future stables will come out a bit faster. Unfortunately, we are pretty busy right now, so we didn't have time to write up a super detailed changelog - most of the good stuff is behind the scenes!

Here's some highlights from the past year of updates - there's far more than listed here.

LEX

LEC

A lot of bugs were also fixed. Too many to list!

Legendary Explorer 6.3

This is a summary of major changes from Legendary Explorer 6.2 to Legendary Explorer 6.3. It's been so long since a major release that there are far too many items to list here; this only covers the major user-facing changes. There are far more minor changes that are not included here, most of them under the hood.

Legendary Explorer - 6.1

Legendary Explorer 6.1 is an update to the stable build of Legendary Explorer. We have spent considerable time improving things under the hood since the initial release back in July.

As always, if you want the latest features and bugfixes, use the Nightly version from the Tools menu in ME3Tweaks Mod Manager, which is always built from the latest code on the Beta branch.

If you want to keep up with information about Legendary Explorer development and news (such as when we merge a feature branch into nightly, which can introduce significant instability), join the ME3Tweaks Discord.

New Tools

Plot Database

Plot Database is a new tool for browsing the plot databases provided by BioWare for each game, and for creating plot databases for your own mods. Plot elements are displayed in a hierarchical structure, and can be searched, or filtered by element type. This tool is still a work in progress.
image

You are also able to create, load, and save plot states for your own mods, which can then be viewed contextually in other tools in the same manner as the basegame states. Mod trees are stored as individual .json files that can be shared with collaborators or on mod pages. Support will eventually be added for syncing custom mod plot data with the ME3Tweaks server.
image

Texture Studio

Texture Studio is the toolset's mod-wide texture replacement tool. This tool is still pretty new and likely needs some more work. You select a 'workspace', which is typically your mod folder. A texture map is then built for your workspace, which calculates where each unique texture (unique being the Instanced Full Path of a texture) is used. This differs from Mass Effect Modder, which uses the CRC of a texture to identify all places where that specific texture is used in the game, regardless of the Instanced Full Path (some textures are duplicated in the game).

image

You can then see all instances of a texture by its in-memory name, and change all instances at the same time to a specific TFC. Instances in red are items with mismatched CRCs; that is, the texture data between instances of this in-memory path are not the same, and should all be changed to be the same, or the offending ones be renamed to be unique - otherwise, you don't really know what's going to load in-game.

image

Right now this tool is designed for use with ME2/3 and LE1/2/3. ME1's texture system is a real nightmare to work with. In the future we would like to cache the texture map to disk to make it spend less time scanning every time you use the tool.

Legendary Explorer - 6.0

Legendary Explorer is an upgraded and rebranded version of ME3Explorer - ME3Tweaks Fork, so we have kept the old versioning system. As such, this is the next major version of the toolset after ME3Explorer 5.1.

Legendary Explorer (LEX) supports both the Original Trilogy (OT) and the Legendary Edition (LE) version of the Mass Effect series of games. It is recommended that all mod developers move to Legendary Explorer, even if you are not planning on modding the LE, as all active development will be taking place on LEX.
