I am trying to rig long year of dog.

  1. It needs to bend along chain of bones
  2. And its base bone should be able to rotate the whole ear without twist.

I understand why there is deformation but i need to understand why there is twist in whole ear when only base bone is rotated

enter image description here

Please check this EAR Rig File and help me with twist.

You have two sets of bones DEF and MCH , MCH inherit the rotation from the root bone , while the DEF bones copy the location and the orientation of MCH but they keep their own rotation ( DEF bones are the ones controlling the mesh ) when you rotate the root or one of the MCH bones the DEF will follow but maintain its rotation ( which seems like the twisting effect )

A quick solution is to choose the first DEF bone and parented to the first MCH bone ( also check inherit rotation )

That deformation occurs because you didn't add weights in weight paint mode.

  • Select the armature and change to pose mode
  • In pose mode with the armature selected click the mesh
  • Change to weight paint mode
  • Select bone by bone and add vertex weight
