I've started work on character models for my new film. I've not really needed them before so it's been a bit of a new experience. Luckily I worked with character models on the Texaco work I did ( http://www.balancedthere.com/2007/12/peculiar-adventures-of-hector.html ) so that's useful to know what is useful to have when it comes to animating character models.
Think I'm going to opt for a pen/brush tool hybrid to create the look I want while keeping it relatively easy to animate.
