How to and tools overview, make animations etc.

I am missing a general how-to overview of UR4, reading the forums i found that there is no ways to MAKE animation, you can use them only - but searching YT I find that there is a tool called ART and also a took called PhAT. One should be for animations, and the other for assets (craracters or props, I assume). Also, still goring over several tutorials, I find that UR4 have built in some neat debug options/functions…

How do I get an overview - untill i found ART and PhAT, I was looking at DAZ3D, iClone/Character creater, etc… but how faar can one get ‘with in’ UR4.
