Hi there,
Has for the export of FT files with a big resolution, I discover that you must have a pretty big computer to do it in 1 shot. I've got a 6 month old computer with 2 gig of memory and to get the good look of my FT map in cc3, I've decide (after many test) to zoom the map and save each zoom windows has an individual file. It gave me 12 files for a total of 70 Mo. Then I use Photoshop to put them together in a png file of 45 Mo that I then import in cc3.
Here is the link to my map.
Hope It helps you,
Alucard.
