I'm playing with the NLA editor so I can use action strips, but I think I don't understand how it works.
From what I understand, I can see the NLA (global) animation only if there is no action opened in the Action Editor.
I can edit an Action Strip by right-clicking it then Start Editing Stashed Action from within the NLA. It is now open in the action editor. But I don't see anymore the global animation of the NLA so it's difficult to work correctly.
Is there a way to edit an Action Strip while the global animation plays ?
