Creating Occluder from a complex mesh automatically

Godot Version

4.2.2

Question

Just recently, I noticed that Trenchbroom, the program I use to create maps (which are imported into Godot using the plugin Qodot) only creates Occluder instances for a specific layer. The issue is that I want an instance of the occluder for each layer.

So, given the mesh, can I create an occluder instance without having to manually set up all the shapes? The model is quite complex (it’s a map with a lot of passages and walls), and it would be kinda hard to create all the occluders, so, is there a way to do it automatically, by just giving the occluder the MeshInstance node?

Thanks in advance
