2023.06 - LancerEdit Special

10 Jun 14:38
Choose a tag to compare

This is a release introducing plenty of new LancerEdit features.

Please use 2023.06.1 on Windows, this build has a critical bug with file dialogs

Note: 32-bit windows builds are no longer provided from this release forward. If you require a 32-bit build for windows, it is still possible to compile it yourself, by passing --with-win32 as an argument for build.ps1

Release and daily builds for windows are now compiled using the mingw toolchain, so MSVC 2012 and 2015 redistributables are no longer required to run Librelancer.


  • Brand new model importer with support for .gltf and .blend files (with blender installed). Includes .sur generation based on maxlancer code, and vmeshwire generation.
  • New 'Data' menu, allowing you to view various parts of a Freelancer install/mod when loaded.
  • System Viewer and Thn Player moved to tabs in LancerEdit, opened from the data menu.
  • Infocard Browser moved to data menu, and now allows you to edit and create new infocards.
  • Thn files can be opened from the File->Open menu (set filter to Thorn files) to open with a text editor. If game data is loaded it will have a preview on the left-hand side. (Thanks to @mcgoober)
  • Fixed crash on minimize with MSAA enabled
  • Fixed distortions in model viewer when Render tab is open
  • Fix some edge cases with matrix/euler conversions, hardpoint editing is more reliable.
  • Removed an accidental Thread.Sleep in the DDS creation code, should be a lot quicker now.


lleditscript may now be passed the -m flag to load any script within the lib/editorscripts folder. This now comes with 3 built in scripts.

  • importmodel (call with lleditscript -m importmodel). Create .3db or .cmp files from .gtlf/.blend models on the command line.
  • img2icon (call with lleditscript -m img2icon). Used for generating .3db icon files from image files on the command line.
  • thorn2lua (call with lleditscript -m thorn2lua). Used for decompiling .thn files, this replaces the thorn2lua executable.


This application has been removed, and the functionality merged into LancerEdit.

  • Added delta compression to netcode
  • Refactored parts of the renderer for simplicity and maintainability, particularly in setting camera state (fixes distortion in LancerEdit).
  • Shader variants are generated offline in the shader tool, instead of with #defines at runtime.

This release fixes some architectural issues causing crash windows to not appear, redesigns the launcher, and improves the editor. Notably:

  • Texture import has an option to flip textures vertically

Librelancer 2018.12

Librelancer 2018.12 Pre-release

This release focuses a lot of cleaning up the core engine code and moving parts out to C/++ libraries. It also includes a user interface for tooling based on dear imgui,

Shiny New Things

  • MIT license for easier integration into your own projects
  • LancerEdit, a cross-platform, modern editor for Freelancer UTF-based files which includes things such as...
  • Collada-based mesh authoring support!
  • System Viewer is now split out into the SystemViewer binary. The Launcher is now a pure engine instance without tooling.
  • Greatly improved performance since 2017.10.
  • Proper support for mipmaps in MIPS and MIPx nodes.
  • Turrets assigned to station loadouts render
  • Ship-mounted weaponry that can be aimed
  • Considerably greater compatibility with THN scenes (still WIP!)

Windows Notes

This release for Windows requires both the 32-bit and 64-bit redistributables for Visual C++ 2012 and 2015. These are not included in the archive. For maximum compatibility please install both x86 and x64 versions

(EDIT: added 2012 for freetype, this will be simplified in future versions)

This release also requires .NET 4.6 which is not included in older versions of windows.
Link: .NET 4.6

This release removes the mostly broken DX9 fallback powered by ANGLE. Now OpenGL 3.3-capable hardware is absolutely required to run.

Linux Notes

Ubuntu/Debian users are best installing Microsoft's official Mono package from their repository for best performance and compatibility.
Link: Mono

Linux users are encouraged to compile their own binaries with the new system based on CMake/cake. This will reduce incompatibilities with the large amount of native code now used.

Known Issues

  • Occasionally hardpoints are flipped inside out after editing in LancerEdit. I've yet to be able to reproduce this, so if you can reproduce it consistently please let me know.
  • macOS support has been removed from the build system entirely. With Apple's deprecation of OpenGL this would require a dedicated maintainer to rewrite the graphics backend.
  • Xwt is crap and broke my Crash Window on windows after I fixed it, so to get crash information you'll have to launch from cmd >:C
