Hi there. I'm not too sure what you mean. Signals are a purely Godot concept, so that would have nothing to do with the GLTF file format or Blender.
—when I re-export from Blender, it breaks. I connected them using code instead, so it's not a big deal.
Do you have a channel where I can ask questions about the add-on, or is this the right place?
Recently I was wondering if it's possible to create a null object or any other kind of object in Blender that would be imported as a Node3D in Godot. I'd like to use it as a coordinate reference for moving objects during the game. I can add it directly in Godot, but for organization it would be handy to add it in Blender instead.
So far I'm loving your add-on—it's helping me save time and create levels with a lot of freedom. Hope I'm not being a bother.
Cheers!
No problem. Discord (https://michaeljared.ca/) is the best way to chat about the addon. But I may be able to answer this one now, as bi-directional export/import isn't really supported (yet).
You should be able to export empties from Blender and use them as Node3Ds.
It's no trouble at all, and I am glad it has been useful so far.
