Simple Level Editor

⚠️ NOTE: This project has been superseded by a new level editor and will not receive new updates. The new level editor is currently not open source because it is part of my proprietary engine. The new editor contains better state management, improved formats, and bug fixes.

Simple cross-platform 3D level editor written in C# and F# using .NET 10, OpenGL and ImGui.

Try the latest alpha version here.

The GitHub releases only list Windows builds for now, but a Linux build can easily be made. You only need the .NET SDK to compile the project.

There is also a NuGet package for reading level and entity config files:
