Keying Set Failed To Enter Any Keyframes - HELP!

This issue has been coming up too often since switching to 2.5x.

Does anyone know where I can learn the ins & outs of keying sets?
I’ll be in the middle of an animation project and suddenly I can no longer insert keyframes on certain bones or objects. With my current knowledge it seems impossible to predict when or why. It just seems to happen at random. When that familiar error message starts popping up “Keying Set failed to enter any keyframes” I’m pretty much screwed. It may as well be a corrupt .blend file because I have not yet found a way to get things working again.

I’ve tried deleting keysets (as suggested on this forum) with no success.

I want to understand what is causing this error to start happening and how I can prevent it. …or how I can fix it. Maybe there is a hotkey that removes bones’ ability to be keyed. If that’s the case how can I disable this crippling function? I’m literally animating with auto-key turned on and just transforming and rotating bones. That’s about it. And yet somewhere in there I lost the ability to key bones.

Please help!

Thanks.

I would first open the graph editor, set to selected, and see the keying set in detail …

Haha! I have the Graph Editor open on the regular so I didn’t expect to see anything unusual. Now that you mention it, I see the bone I was having trouble with is locked! That’s embarrassing. No wonder I couldn’t key it.

I swear this issue has come up without bones being locked, but now I’m going to double check each time. Thanks.

I’d still like to learn of Keying Sets if anyone knows where some of this good ol info is kept. I haven’t had time to search for it thoroughly yet. But will appreciate any info any of you can spare me.

Also, does anyone know the hotkey for locking bones and objects? I wonder, if there is one, if I’m accidentally pressing it.

Tab can lock/unlock sets or individual channels.

Thanks. Tab is good to know.

I’m actually still getting this error message on certain bones and there are no locked channels. It happens when I try to key frame certain individual bones by pressing the I Key. Like I mentioned before, I’ve never had issues with this in previous versions of Blender. Oddly I can still key those same bones by using auto key. Actually it’s the only way it seems to work at times. Anyone know why?
