If the UA character material was released after January 1, 2018, it is or will be available here. (I think Badeye said it would be up a week after release). In the character builder, on the Home page, make sure "Use Playtest material" is turned on, and you should be able to see UA material.
Note that with the exception of classes and subclasses, you can "homebrew" any UA character material (race, feats, spells, etc.) you want, as long as you don't try to publish it. Eventually you will be able to homebrew subclasses, but not full classes.
Is there a way to create a pc using UA material in a similar manner to say if you were using the PNB or XGE?
