Why did my armature disappear? I built an armature. After completing it, I moved it to another layer. Now all my bones are gone.
If you look at the video, you see the mech on one layer, and as I select the layer where I moved the bones to, they are not visible.  In the mech layer, I see the black lines connecting everything, but now I can not pose the mech as I have no access to the bones.
In the video, I go through each mode and use Alt+H, but nothing is happening.
Where are the bones?
The bones layers are different from the mesh layers. To find your bone layers, you select your armature from the outliner then under the skeleton menu under the properties panel you will find the bones layers there.
