Hey R@nSiD, thanks for the reply.

I have a video tutorial that takes me through the process of building the bones/joints etc, and I have the spine in place.

My problem is down to the movement of the body when I move the various joints. In the tutorial the body seems to bend naturally and twists just as a human does with the waist staying in place and shoulders twisting nicely. It looks very natural.

However with my penguin the body is made up of only one polygon, therefore it does not 'bend' in the same way. I have tried splitting the body into several parts where each bone starts and ends. i.e. have split the polygon into sections such as head, neck, body etc. But each part still moves in a very rigid way and does not 'bend' in the way the human figure does in my tut.

Apologies if I sound confusing as I am not sure how best to explain this! Hopefully someone understands what I mean! Thanks in advance for any advice...
