I personally think that feature like "Baking CSG" should be in Godot by default
Godot CSG Exporter
A downloadable asset pack
For more assets like this, follow my itch.io page!
Godot 3.x editor plugin to export CSG Meshes as Wavefront (.obj) files.
The source-code is also available on the GitHub repository: https://github.com/henriquelalves/GodotCSGExporter
Disclaimer To fix the CSGMesh material exporting, I merged mohammedzero43's CSG exporter with some slightly tweaks; the original code can be found here: https://github.com/mohammedzero43/CSGExport-Godot. Thanks for letting me use it!
How to install
Add the addon on your Godot project (you may copy the addon from the project folder, or install it via Godot's AssetLib). Then activate it on the project settings "Plugins" tab.
How to use it
Why using it
CSG Meshes are quite useful to prototyping and making quick modifications on levels, but sometimes you may want to export the mesh made in Godot so it can be edited in other software (e.g. Blender).
