Reply To: I can not key everything with I key at the first passing pose. It returns an error “Keing set failed to insert any keyframes”. How can I solve it? Thanks

You can use any keying set you like, but the ‘available’ will only key the channels YOU want.

So if you delete a channel, it stays deleted.  If a channel is locked it will not add keys to it.

It keeps things clean, rather than recording a bunch of animation curves that are redundant.
