Engine

Unreal Engine

LoreOwl finds your engines, cooks and packages with RunUAT, and adds a Vault window to the editor.

What LoreOwl does with it

Finds your engines

Epic Games Launcher installs and registered source builds.

Respects the project's version

It reads EngineAssociation in the .uproject, and warns before a project would be converted.

New projects

Blueprint-only 2D, 3D and blank templates, from Unreal 5.0 up. No Visual Studio needed.

Clean builds

RunUAT BuildCookRun on a fresh copy of the project, so every build is a clean cook.

Analytics

The LoreOwl Analytics plugin is added to the build copy. Blueprint-only projects compile it, which needs Visual Studio.

A Vault window

Window → LoreOwl Vault, in the editor.

The build

How it runs
RunUAT BuildCookRun with -cook -stage -pak -archive, for Win64 or Linux.
Configuration
Shipping by default. Development when you tick Debug build.
Compiling code
-build when the project or one of its plugins has a Source folder. Otherwise the editor is not compiled.
Left out of builds
Binaries, Intermediate, DerivedDataCache and Saved.
Cancel
Stops UAT and everything it started.
Time limit
A build stops after 60 minutes.

Version control

  • Content/ is versioned. Binaries, DerivedDataCache, Intermediate, Saved and build folders are ignored
  • Vault assets go to Content/Imported/
  • Placing a .uasset or .umap warns you that it only opens in the engine version that saved it

What it does not do

  • Builds for Windows and Linux only. No macOS, web, mobile or console.
  • LoreOwl does not install Unreal. Use the Epic Games Launcher.
  • No feedback form, obfuscation or pre-build checks. Those are Godot only.
  • Cook settings beyond Shipping or Development are not configurable.
  • The desktop app is Windows only.
