Previous Figures Export Script
I still occasionally enjoy working with both Genesis and Genesis 2 figures. (It takes about 1/3 of the time to pose)
However, when exporting the obj for sculpting in either mudbox or ZBrush the UV's export all stacked into the first tile. G3 & G8 export with each map on a different tile.
Does anyone know of an export script or any product with an export script that will spread the UV maps over different tiles?

It doesn't actually matter - the UVs are stacked in t base mesh, before yu sculpt it, anyway. If you want to separate them I believe Mudbox can do the job, as can just about any other modeller - you simply need to select all the surfacs that belong on a map and move them a whole number of units, usually along the U axis.
there are UDIM UV's for the earlier figures on shareCG
I could just kiss you right now!!!!!!
