zbrush/sculptris question

I was playing around with sculptris today (trying to figure out if it might be worth sinking money into zbrush). I modeled something horrible, applied very ugly paint, and then imported it into Blender. In Blender, the mesh does not have any texture. Is this because Sculptris on uses obj or is there a way to export the texture separately and apply it in Blender?

Also, what formats does zbrush and Blender support in common? I’m trying to figure out a workflow using Blender, (some form of sculpting software), Gimp, and eventually get everything into UDK.

Thanks.

Both blender an zbrush can import/export models as .obj files and texture maps as bitmaps. You can also use the goz addon to interchange models with a button press
