group hierarchy not working

[pantsgt]

when i group brushes in trenchbroom and build the map in godot, i get 3d nodes at 0,0,0 on all the groups and the brushes are all in worldspawn

This is by design. Only entities other than worldspawn will be separated into Groups and Layers. Multiple Worldspawns will not be created. From the FuncGodot Manual:

If true, will organize Scene Tree using Trenchbroom Layers and Groups. Layers and Groups will be generated as Node3Ds. All structural brushes will be moved out of the Layers and Groups and merged into the Worldspawn entity. Additionally, any Layers toggled to be omitted from export in TrenchBroom will be freed on map build before the Layers' children can apply func_godot_properties or call _func_godot_apply_properties() and _func_godot_build_complete().

Be sure to read the manual if something is not working the way you expect it to, as it may be by design:
