Octopus tentacle with b-bones

Even though I’ve added some extra loops to the model it looks bad in joints.
Is there a way to make smooth tentacle?

make sure that the subsurf modifier is below the armature modifier, or else it will subdivide then deform rather than deform then smooth.

good luck :slight_smile:

Sometimes “Preserve Volume” option on the Armature modifier can correct this kind of problem on articulations.
