4th update:
Actually first i was created the tentacles as straight, cause i planed to rig them..
so that its easy to give curve and bend shapes on tentacles but it was bit difficult to me. because.. for each tentacles we have to create bones than have to bind than only we can rig. and first of all im not going to animate this, so i changed the way.
i just delete the tentacles and recreate that all with curve and bend shapes while modeling. now it was quickly complete and saved my more time.
Hope u like it, wil update soon.
c & c welcome
