Zbrush - Matcap to Low poly

Jonas Ronnegard

I came across this a couple days ago

http://www.zbrushcentral.com/showthread.php?170886-MatCap-Baker!-unofficial-Information-Installation

which seems to make it easier and faster to bake down your matcaps in zbrush,
but I have some questions, I haven't really baked anything inside of Zbrush before
and in all the tutorials covering this method seem to be baking stuff on to their High poly,
or going back to their lowest sub d and creating a uv map inside of zbrush.

How do i go about getting it baked down on to my already made low poly uvs?

Hope someone can help me out.

You can either project the highpoly detail onto your low-poly within Zbrush or alternatively Bake the maps into your highpoly, save export it into Xnormal and bake vertex colors to your low-poly.
