Question

Hey, I need to exclude some animations from importing from a .blend file

  • I must not delete them from the .blend as I use them as source for the final animations
  • Only the ones I want are in the NLA, but godot imports everything anyways
  • Im using GameRigTools, that means I have 2 skeletons, one with Rigify and a simples one, the only one Im importing is the simple skeleton, that part is working correctly
  • I`m sure the NLA tracks for the other skeleton is empty
  • The “-noimp” tag does not work with animations unfortunately
  • I tryed a post-import script, but it seems I dont have access to the animations in order to delete them
  • There is no checkbox to skip import in individual animations as there is in the skeleton

Anyone can help here?

It seems that these unwanted animations are not imported if I select the “Visible” options to “All”, which does not make much sense to me :thinking:

@tool
extends EditorScenePostImport

const REMOVE_ANIMATION_REGEX: String = "-noimp$"

func _post_import(scene: Node) -> Node:
	cleanup_animations(scene)
	return scene

func cleanup_animations(scene: Node) -> void:
	var anim_player := scene.find_child("AnimationPlayer", true, true) as AnimationPlayer
	if not anim_player: return

	var remove_regex = RegEx.new()
	remove_regex.compile(REMOVE_ANIMATION_REGEX)

	var mixer := anim_player as AnimationMixer
	var lib_names = mixer.get_animation_library_list()
	for lib_name in lib_names:
		var anim_lib: AnimationLibrary = mixer.get_animation_library(lib_name)
		if not anim_lib: continue

		for anim_name in anim_lib.get_animation_list():
			if remove_regex.search(anim_name):
				anim_lib.remove_animation(anim_name)

Very useful, thanks! I got some support animations I use only on Blender but they get exported to Godot as well. I made some adjustments to the script:

@tool
extends EditorScenePostImport


# Constants
const PREFIX := "_"
const SUFFIX := "-noimp"


# Built-in overrides
func _post_import(scene: Node) -> Node:
	_cleanup_animations(scene)
	return scene


# Private methods
func _cleanup_animations(scene: Node) -> void:
	var anim_player := scene.find_child("AnimationPlayer") as AnimationPlayer

	if not anim_player:
		return

	var lib_names = anim_player.get_animation_library_list()

	for lib_name in lib_names:
		var anim_lib := anim_player.get_animation_library(lib_name)

		if not anim_lib:
			continue

		for anim_name in anim_lib.get_animation_list():
			if anim_name.begins_with(PREFIX) or anim_name.ends_with(SUFFIX):
				anim_lib.remove_animation(anim_name)
