GRLE 16 Channels

[TrooperLorenzo]

Hey all,
I have a very strange problem with my GRLE converter when i am trying to convert the cultivator_density.gdm in a map conversion process from FS19 to FS22. Problem is that it does not generate the .png file as expected, it only lists some general information, see below.

"Gdm file info (C:\Users\William\Desktop\fs19_NHMAP_DOWNLOAD\maps\map01\cultivator_density.gdm):
8192x8192px
16 channels
2 maxBpp
32 chunk size
2392658 bytes
2 compression ranges: [0-4] [5-15]

Press any key to continue . . ."

I seem to understand that this could have something to do with 16 channels, although i have no experience with this and would like to know is it is true, and if so - How do i decrease the number of channels on my map that i am converting from.

Best regards
