Allright, when I use the AUTOPO wizzard and I'm at the step where you can "paint" the density modulation area thingie - is there any way to save or load the selection you painted as more dense? My problem is, I've got a pretty big voxel object (terrain basically) that I want to convert to a mesh but it's pretty much a trial and error process until I get the desired result. And each time I run the AUTOPO wizzard my density modifier selection is wiped clean and it is really tedious to mark all the denser areas over and over again.
