I think what some people are trying to get over is the welcome ability, to be able to just pick up a brush and paint with it… as opposed to putting paint in an airbrush, and having to correctly control the mix of air and paint to get a stroke… When you use Mudbox, you find this ability to just work very apparent… Somthing that is not so apparent for many people, when using Zbrush.
Now dont get me wrong, I personally dont have any problems with Zbrush now, but when we had to use it at an fx company I worked in, it turned out, getting to grips with it was not a 10 minute thing… If that was MB, i think it would have turned out ok…so for me the beauty of Mb is the out of the box simplicity… Im aware now… that these discussions are quite heated, and people have their attactchments to the tools they work with… This is somthing I learned to distance myself from. I feel its best to view software as a tool, every once in a while you find a tool you like the feel of, but to use it where others are more convienient can be detrimental. What really matters is what your doing, So for people who want to sculpt… Digital Sculptors, MB is a godsend… no faffing about, no fuss no mess…
I think this is mainly what makes people rave about it so much…
And the cancer, well, I think there could be alot of patent issues considering the amount of people involved in this discussion
