hi,

i was just quickly wondering if i can somehow force my armature to be resetted to the pose in in edit mode

i messed up my huge mesh and the best way would be to simply force it back into the position it is in edit mode, becayuse otherwise its impossible to get it like that again and ill have to restart from scratch

help is desperatly needed! plz nayone!
