I want to use an armature that i have already made. The character i want rigged is scaled a lot smaller than the armature. I scale up the character to the size i want, then set the scale using ctrl a. then when i try to use the automatic weights to set up the armature, the character reverts back to it original scale and the armature stays the same as it was. What am i doing wrong?
Did you scale the character in Object Mode or Edit Mode?
Does the rig have Apply Scale to it as well?
a link to the .blend file will help
Good luck!
