gameObject.activeInHierarchy will return false if the GameObject is a prefab and not instantiated in the scene.

Seems to work with Unity 2021.3.+ without these changes.
@hybridherbst, whats your opinion? it would only benefit the compatibility support for 2020.3

I remember we had to do changes in the past to make that usecase work (exporting from Project), despite activeInHierarchy being false.

@ArminRoiderKubat could you please provide reproduction steps and a reproduction .unitypackage? Thanks

Here is the package and the exported glTF files.
PR745.zip

CubeScene.gltf will contain animations.
CubeProject.gltf has no animations.
Both are exported from the same prefab. The first was exported by selecting the Prefab instance in the Hierarchy window in a open scene. The other by selecting it in the Project tab.

Steps:

  • Open the SampleScene, select the CubeScene GameObject and "Export selected as glTF".
  • Select the Prefab CubeProject and "Export selected as glTF".
  • Compare both files. The second export does not contain animations.
