Baldur's Gate 3 Script Extender vs MWSE

Baldur's Gate 3 Script Extender adds Lua and Osiris scripting support for mods in Baldur's Gate 3. A mod can enable Lua with a feature flag and load bootstrap scripts for the client and server. The extender keeps separate Lua states for the game server and each client, and its console can run Lua code and registered console commands. Configuration options provide Lua and Osiris debugger interfaces with configurable listening ports, and logging options can write Osiris activity, runtime output, story compilation and compilation errors to files. An EnableAchievements option can re-enable achievements in modded games. SendCrashReports defaults to true and uploads minidumps to a crash report collection server after a crash. Installation involves extracting DWrite.dll into the game's bin directory. The extender updates when the game launches by downloading and applying an update. It supports Windows and Linux via Proton, but does not run on game versions older than patch 5; new versions target the latest game version. It is free to obtain under a license that includes the MIT License and a Commons Clause restriction on selling the software or substantially derived products and services.

MWSE adds scripting capabilities to The Elder Scrolls III: Morrowind beyond those provided by the game's Construction Set. It gives mod authors ways to add features or behavior that would otherwise be impractical or impossible. From version 2.1, modifications can use Lua for event-driven behavior, with hooks for events such as level-ups, collisions and world activations. MWSE exposes APIs through Lua 5.1, with extensions from Lua 5.2 and Lua 5.3. Mods are not sandboxed, so they can include packaged Lua modules and native code. Included patches raise the mod limit from 256 to 1024, and crash dumps and logs help diagnose mod problems. MWSE is free software under the GNU General Public License and comes with no warranty. It supports Windows and Linux through Wine. Installation requires the x86 Visual Studio 2022 Redistributable, Morrowind Code Patch and Morrowind Graphic Extender XE. MGE XE bundles MWSE-Update.exe, which downloads the latest automated build. The project directs scripting advice and discussion to the Morrowind Modding Community Discord.
