Rigging and model probs..... 25/02/08

Ok so I have been using a rigging tutorial that Jeff found on the internet. Its a very good tutorial, simple to use and easy to understand. However I got to a certain point when I realised that I wouldnt be able to use this rig for my particular model. I smooth binded it a couple of times to see how it was working and it just doesnt work with the model. I feel there is to many technical problems with both the rig and the model that I have made, and at this point it is to late to start again. So what I think the best thing to do is to use a pre set rig for the purposes of the outcome of this brief and then in my own time start this character again and develop it in my own time.
