Accidentally hiding a bone in a proxy armature cannot be undone with ctrl+z.
Closed, ArchivedPublic

Description

Version: 2.70 test build (win 64)

How to reproduce:

  1. Open a new file in blender and link the group in the provided file (or any group with an armature, really)
  2. Make a proxy of the armature.
  3. Go into pose mode, select a bone, and hit H to hide it
  4. Note that using ctrl+Z does not undo the hiding of the bone.

Given that the hotkey for hiding is right next to the hotkey for moving (H and G, respectively), this has the potential to seriously confound new users learning character animation in Blender. Alt+H of course works, but many users do not know Alt+H. Their initial response will be to hit ctrl+Z, like after any mistake in Blender, and this ought to work just as well.

BTW, my company is producing an online Blender animation class for children. I understand the devs' reluctance to fix minor bugs so close to an official release, but we're launching quite soon so I'm worried that if this bug survives into version 2.70, it will make children cry. Sobbing, they will repeatedly press ctrl+z to no avail, believing that their character's bone is gone and their animation is ruined forever.

I don't mean to implicate the devs here. This is entirely my fault for attempting to teach advanced Blender animation to kids! You've already fixed so many bugs that our course has improved wonderfully; it would be terrific if this one last bug were squashed as well.

Yeah, annoying indeed... :/

Dev notes: For some reason, undo does not affect the 'Hide' property… also, most bone's settings are disabled in UI (including the Hide toggle), yet I could not find anything in py or RNA code that would explain that disabling… I’m a bit lost here :(

It's not supported by the design actually. Hiding the bone works with armatures, not poses. It's not so simple to add hiding flags to pose, so considering it a TODO: http://wiki.blender.org/index.php/Dev:2.5/Source/Development/Todo/Animation#Rigging

Meanwhile you can use Alt-H to bring bones back. And i've also added an info message when you hide bones of a proxy which tells you how to bring them back.

Thanks for the report, but closing it now.
