Your mod seems to have problem with converting white colour in map to terrain. This highly visible in Antarctica or Greenland which are completely broken.

That's correct, the current algorithm only tries to guess the following tile types:

"deepwater",
"deepwater-green",
"water",
"water-green",
"grass-1",
"grass-3",
"grass-2",
"dirt-3",
"dirt-6",
"sand-1",
"sand-3"

I have no plants at the moment to update these. Might happen some time in the future, but for now that's it. The code is open source though, so if you want to tinker with it yourself, you're more than welcome.

Sorry for the disappointing answer.

No problem, i think i`ll just simply replace white on map.
