I've used Hash. Texturing is great. Modelling is a nightmare and on top of that it's an unstable program. I worked with it constantly for months and never got satisfactory results trying to model realistic human figures. No matter how hard you work or how good you are, Zygote does a better job and their models are easier to work with. Hash is great to use to learn bones and the basics of advanced animation techniques but it is not a production tool.
