For those of you who took advantage of the offer from 3DBuzz and got motionbuilder....what do you think of the application? Have you found it useful? Have you had any troubles with it? What are your favorite features of the app? What don't you like or wish that it did? Is it as easy to use as it seems? Just looking for opinions here, as I'm looking to buy it, but I want to know beforehand if its going to be a waste of my time.... Thanks. Evo
