After applied as rest position mesh doesn't move I'm really new to blender and english isn't my native language so i'll try to be as clear as possible. I'm making an animation for an university exam, i made a simple videogame character that i'm going to animate.
The character is an archer so he got a rigged bow and arrows as props; he wears a shirt, a vest, trousers, gloves and boots. All of them are different elements, i didn't joined the wearing stuff because i thought it could have been more simple to manage and edit the single elements.
After i used the Rigify Modifier i tried to put him in an idle position and when i had done it  i had accidentally applied the pose as rest pose. Since then, the only thing that moved was the rig but the mesh seems to stand still and even if i try to move the rig in pose mode it doesn't move.
There are many question that i would like to do, but essentially: Why the meshes doesn't move along with the rig anymore? And where i can find that bloody rest pose!? (I just selected &quot;Apply as rest pose&quot; because i was thinking maybe that was the only way to make that position the default pose in viewport and a good starting pose for my animation)
If you have nothing to loose, delete and regenerate your rig.
When i reset my rig i select all the bones and then
Select all the bones, in pose mode with A. Then, hit:
ALT R to reset all rotations,
ALT G to reset all translations,
ALT S to reset all scales.
Or select all bones (A) and hit space. Then search for &quot;clear pose&quot;
