MJOLNIR Tag Editor changelog
Browse and edit the Blam tags, textures, audio and scripts inside your installed game.
11 releases · latest v0.9.0 · Documentation
Choose which installation you are editing
The setup form now takes the game folder itself, and the installation you have open is named at the bottom of the left panel, with a way to change it.
Swap textures from inside a mod project
Replace any texture's pixels with your own image from inside a mod project, and have it travel with your tag and script edits when you test, export or publish.
Read, edit and compile the campaign's mission scripts
The campaign's original mission scripts ship inside the game. The Tag Editor now shows them, lets you edit them, and compiles your changes back in.
Twice as many textures preview
Around half the game's textures would not preview at all. 4,787 of 4,844 now decode, up from 2,421.
Hotfix: audio plays in the installed app
Fixes 0.6.0, in which the audio browsing added one release earlier could not actually play anything once the app was installed.
Browse and play the game's audio
The Tag Editor opens the game's sound archives — around 6 GB it could not read before — and lets you browse, name and play 194,559 Wwise audio files.
Live tag editing in the running game
Change a tag value and see it in Halo Campaign Evolved immediately — no rebuild, no repacking, and no restarting the game.
Link a hub account instead of pasting an API key
Publishing now uses the same pairing flow as the launcher — approve a code in your browser — instead of minting an API key by hand and pasting it into a text box.
Author, test and publish mods without leaving the editor
Mods become saved projects rather than one-off exports: keep a list of your edits, test them in the game, and publish to the MJOLNIR Hub from inside the editor.
No Oodle DLL required
The Tag Editor now reads the game's compressed containers on its own, so you no longer need to supply a proprietary Oodle DLL before it will open anything.
Browse and edit the game's tags and textures
Browse every asset in your installed copy of Halo Campaign Evolved, read its Blam tag fields in a Guerilla-style form, preview textures, and export edits.
