Godot Version

Question

When importing 3d humanoid model from a glb file, godot will generate a scene looks like this:

20260310_21h32m34s_grim
20260310_21h32m34s_grim405×458 18.2 KB

The Scene and bot are actually redundant. How to remove one of them?

List the attempts I’ve made:

  1. create new inherited scene. But I got can't operate on nodes the current scene inherite from! when I tried to edit bot or Scene node
  2. copy the neccesary nodes, which are the subtree rooted at bot, to a total new scene. This works but I got
The text-based scene at path "res://Arts/Characters/Bot/bot_copy.tscn" is large on disk (2.38 MiB), likely because it has embedded binary data.
This slows down scene saving and loading.
Consider saving its binary subresource(s) to a binary `.res` file or saving the scene as a binary `.scn` file.
This warning can be disabled in the Editor Settings (FileSystem > On Save > Warn on Saving Large Text Resources).

of course I dont want to embed any binary into .tscn file.

Any other ideas? What should I do? Or correct workflow? thx in advance.

You want to link to the binary. Right now you are embedding all the data (mesh and bones) as text in your tscn.
A character of mine looks like this:

Your scene could be the CharacterBody3D. If your bot or my rig should be it’s own node is debatable. But it’s correct so far.
As you can see, my rig, skeleton and meshes are displayed as yellow. Yellow means it’s inherited and not embedded.
Right click on your glb and inherit from that (as CharacterBody3D), always ensure that the skeleton and meshes stays yellow. If they are white at some point, than one of your actions on it made the data unique. That’s where your warning comes from.

EDIT: It has also the benefit, that you can override the glb and your tscn will be updated automagically. Take a look at the file size of your current scene, it could be huge. And check it with the inherited glb, that one should be small.

This workflow is pretty organised , also a bit longer , but if you are using in future KayKit assets might save you headaches.

BTW is your bot not have any animations ?

In Advanced Import Setting, we can assign a script to do any self-defined setting. See link.

Here I tried:

@tool
extends EditorScenePostImport

func _post_import(scene):
	print("humanoid imort post script")
	remove_redundant_skeleton_parent(scene)
	return scene

func remove_redundant_skeleton_parent(scene):
	var skeleton = scene.find_child("*Skeleton*")
	if skeleton == null:
		print("didn't find skeleton")
		return
	var skeleton_parent = skeleton.get_parent()
	print(skeleton_parent)
	if skeleton_parent == scene:
		return
	for child in skeleton_parent.get_children():
		child.reparent(scene, false)
		child.owner = scene
	skeleton_parent.free()

This achieved my goal. The inherited imported scene looks like:

This look good.

I use animationlib imported from other glb file in this project
