Cheers!

Why are you trying to use a gfx, I think, is a better question.

Once you have an image loaded you can save it(saves automatically as gfx) or export it with a .gfx extension- both must be done via code.

Hi,

For use of images in your projects, you just need to drag and drop them to the editor (project region view).
If you really want for some reason to have Image with GFX extension on your disk, then do something like:
Image img; if(img.ImportTry(..))img.save("file.gfx");

Alright I'll give that a go.

The reason why was I read that my skybox images needed to be in the .gfx format or is this no longer true?

Hello!

Perhaps you've read some outdated information? Where did you read this?
Since long time ago, the Editor manages all of the assets, so just drag and drop to the Editor and it will handle the processing for you

To be honest I was just reading around the forums. I went to put my skybox image into the skybox input and it's just coming up black.

Any ideas?

Have you tried adding a single face at a time?

Once you import the image to the editor, please change the mode from hardware/2d/software to cube.

Ah that worked! Thanks guys!
