So i created a Python script for the GIMP. This will automatically generate all the layers needed to save as a cubemap DDS file from a skybox image of choice. In other words, everything (except for the saving part) that you saw me do in my GIMP DDS video tutorial will be done by this script.
You can download the current version of the script here:
https://github.com/pixlsus/registry.gimp...0.3.py.txt
Note: This script has only been tested with GIMP 2.6 and 2.8. If you have a different version than that and have tried out this script, let me know if it worked.
Simply place the file in your GIMP's plug-ins folder, then restart the GIMP.
In Linux: ~/.gimp-2.<version>/plug-ins
In Windows: the GIMP should tell you where under
(Edit >) Preferences > Folders > Plug-ins.
If it doesn't show up in Windows, try following this tutorial

Warning: Be sure to remove anything after ".py" when saving.
