For make maps of displacement 8192*8192 or any automatic "square" textures...

Works like a charm with Aerialod above! (16 384 * 16 384)

I am not sure that PLY format only existing for the moment is very useful because file size result is 2 - 3 gigas!
for the little one following!
I suppose that in the future there will be a more simplified OBJ result!
