Hey everyone, just a quick tutorial on how to open and edit GFX files.
So, in order to create UI modifications GFX files have to be modified. Gibbed doesn’t provide a tool to open them (yet), but thankfully the format isn’t something proprietary avalanche-made format. It turns out, GFX files are very similar to SWF (aka flash) files.
To open them, all you need is a tool which is able to modify those types of files. I’ve found that a great tool for that job is JPEXS Free Flash Decompiler, which can be downloaded here: https://www.free-decompiler.com/flash/
Simply fire up the program and open the GFX file (or drag it onto the program). You’ll be able to modify its contents with ease.
If there are any questions, don’t hesitate to ask.
EDIT: Some shapes seem to appear as colored squares, not sure if that’s the program’s fault or if they are in an unknown file format.
I’m not sure if you can actually add shapes to the file, but removal is easy. Just right-click a shape in the program and click “Remove with dependencies”. That’ll remove it. If you want to replace a shape with a custom one, right-click it and select “Replace”.
