Here are two topics in Blender Stackexchange where I’m considering if there are ways to include different animations in different Scenes, other than some workarounds with NLA and Scene timeline tricks.
For example, I’d like my “Walkthrough Camera” scene to have a door swing open as the camera approaches, but stay closed in another scene, that will instead vary the Sun and lights as the day unfolds. Another example would be a character that has a scene.walks and a scene.runs.
I should be able to assign different Actions, different Keying Sets and different animation keys to Scenes.
That Keying Sets are part of the Scene tab, yet do not relate to a Scene, is in itself confusing.
