Most all of them will load, animate and export X format. The issue then is to get it exported so that it works with DBPro.
My copy of 3DCanvas is totally broken as far as exporting X. I am very frustrated with it, and it probably is my own stupidity, but...I still got a $130 rock.
MilkShape will do it, but I think that the trial only exports a static mesh, no animation. Alot of people use MilkShape.
Blender does it, but is an ugly mess, as far as I am concerned...some swear by it, I swear at it.
Oh, Wings3D, Anim8or, there are tons of them. You can't swing a dead cat without hitting one, actually.
EDIT: Sorry, we're in 3DChat already!
