You could also try scanning as PNG, and see if that works.

Re: [Gimp-user] Exporting DDS for MS FSX Flight Sim

Hi,

On another game, I keep using Gimp 2.8 with the dds plugin (to add by
yourself)

You can try ? May be it's compatible with the game you're working on ?

Hello,

there is at the moment no developer/maintainer for the DDS plugin, have a
look at this links:

Re: [Gimp-user] Wronr reading of 16 bit tiff

Hi Andy,

please open an issue in the Gimp issue tracker and attach an example file:
https://gitlab.gnome.org/GNOME/gimp/issues

Some scanners create  4-channel/12bit encodedimages. Then the 4th channel
is an IR channel that is useful for reducing dust.

Regards,
Tobias
