Codex Level Builder for Godot

Codex is a level building plugin for Godot designed to make 3D level creation as simple as possible. It is perfect for quickly making levels that emulate the Wolfenstein 3D era of level design (but it can also produce slightly more complex geometry).

Codex works by converting its easy-to-use LevelTile nodes into a collection of optimised meshes with the click of a button. Hidden faces and exteriors will be culled automatically, allowing you to simply focus on designing your levels. Each material gets its own mesh that includes all faces of the same type, leading to much better performance. On larger levels, you can use the automatic chunk system to split your level into smaller meshes that are optimal for frustrum and occlusion culling.

Codex also allows you to give each material in your level its own collision properties, so that you can easily implement material-based collision systems such as footstep sounds and bullet decals.

Codex is confirmed to work with both Godot 4.2 and 4.3.
