Hi all, Do you know this tool : global mapper. Perfect way to have a terrain in 5 seconds. 1) open your own data files 2) select your kml 3) click on donwload online data 4) choose SRTM Worldwide, OK 5) Select 3d to check...Crazy isn't it ? So I try to import terrain, in 3dsmax to convert it in .3ds and import it with xpacks in btb... But they are to many data. :freaked-out: And I don't find the good export from Global mapper So I need you ! Do you think I'm in a good way ? Any advises ? Thanks for your comments.
