I am trying to use bones in my model to (at the moment) make it wag its tail. However, when I bend the bones, the tail deforms strangely and won't bend properly. I have tried fiddling with weight painting, but nothing i have tried so far will work.
Images for reference here
EDIT: Sorry, forgot to put a picture that showed the deformation. I've added it to the album ^^. I fixed the bending issue, however whenever I bend it, the inside edge of the tail caves inwards. Also, there is this one stubborn vertex that moves significantly less compared to the other ones, although it is painted in the same weight. This might be a similar thing?
