I've imported an fbx with an "in place" walk cycle from mixamo.com (see below). I then parented the armature to an empty as a way of animating the "in place" walk cycle (tutorial here).
My problem is that with the armature parented to the empty, now I can't find the walk cycle keyframes. No matter what I click on, they will not appear in the dope sheet. In the outliner below, I've clicked on where I think they would be but they don't show up. Any thoughts on why those keyframes are not showing? Unfortunately, I can't get the blend file down to a postable size.
Here's what I mean by "in place" walk cycle:
Why do all the keyframes keep disappearing?
