I have a glTF file (authored by someone else) with many named animation tracks. These are modifying transforms on many different discrete nodes within a scene hierarchy for an automobile. (These are not actions on bones or a rig.) For example, one animation causes all four wheels to rotate, another causes the front wheels to steer left/right, another causes the front left door to open.
I have imported the glTF into Blender. Currently, there are no actions listed in the Action Editor, the Dope Sheet, the Timeline, or the Graph Editor. Scrubbing any timeline causes no action to be applied.
However, I see all the actions listed in the Action Editor's "Browse Action to be Linked" dropdown. I want to select one of these actions, preview just that action (dragging the timeline), edit the keyframes of it, and rename the NLA Tracks to match my needs.
I've watched a handful of videos on the NLA. I understand (I think) that selecting an action in the Action Editor links it to the selected object. I don't want to do that. If I happen to have selected the
Front Left Door Empty and "choose" the Tire Rotation action to try and preview it, the door now rotates 360 degrees. That's not what I want. But, selecting
Front Left Door empty ALSO did not cause any action/animation to show up in any editor.
How do I "select" an Action so that it shows up in the Action Editor, without accidentally linking it to some object in the tree?
I think if you can help me with just that I will be able to tweak keyframes, modify the animations for the action, and move forward.
I'm using Blender v2.83.20, but if you feel I must I can upgrade to a newer version.
