armature deform with automatic weights mesh deform I am new to blender. I was following a tutorial. When I applied "armature deform with automatic weights", the left hand of the cartoon works fine while moving the armature. But the right hand gets messed up.

I have added inversekinetics constraint to move the hand. The armature name is ik.hand.l for left hand. and ik.hand.r.001 for right hand.



The attached blender file is given for reference.

Apply the Mirror modifier, then Apply the Subsurface modifier but only 1 level. You can see from the picture that it's plenty smooth enough. Then in object mode select the mesh, shift select the bones and Ctrl P>Automatic Weights
