CSG converted meshes do not work with OccluderInstance3D as of Godot 4.4.1 — godotengine/godot#104883

There's workaround by DancingEngine:

1. Carve out your level as usual, making sure to keep all CSG geometry nodes separate from everything else. The easiest way to do that is to parent all of your CSG nodes to a Node3D.
2. Copy your CSG geometry to a new 3D scene. Go to Scene -> Export as -> gltf 2.0 scene.
3. Import the scene in Godot. If Godot doesn't recognize it for some reason, open the newly exported scene in Blender and re-export it as an .FBX or .GLB file.
4. Place the baked model back in your main scene and bake its occlusion culling using the button at the top of the OccluderInstance3D viewport.
