I know this tool, but I won't preprocess the heightmaps, I want to calculate the new maps in BB (imagine 100 stars with approx. 5 planets each = 500 heightmaps, doh!). And if you try to stretch the upper map with this tool and put the new map on a sphere it won't fit anymore at the sides.
Torbens planet generator has the solution but I don't understand his source code (the squarep() function).
