I am using NLA and graph editor to edit an armasture (bvh). I AM able to edit individual keyframes, and yesterday I was happily editing and transforming the keyframes on another limb, but today, the keyframes won't budge when trying to use scale along either axis. It's as if the keyframe channels were locked - but they aren't...I have carefully checked.
The NLA strip is green (open stash for tweaks). SOMETHING must be preventing me from editing the keyframes in this way (I want to do a simple scale along Y-axis to tone down some movements), but I am missing what it could be. If it is not channel locks, and the NLA is open for editing, what else could there be?
NB...the armature has bone constraints on them but they are turned off. And the transforms were working on another part of the armature yesterday. I'm stumped. Anything I might have missed?
