I have been asked to create a little tutorial on how to make a cube map in GIMP.
It has been found out that your can use any of the acceptable flavors of texture that Game Guru uses for your model. .png, .bmp, .jpg, .dds
The cube map itself must be .dds format exported with the cube option. It must also contain a specific layer naming convention to work in Game Guru.
Attached is the tutorial in PDF format.
