The Python-Fu plugins here are used in GIMP 3.0 to convert between Minecraft's animated textures and a layered image that is easier to work with in GIMP.
Find your GIMP plug-ins directory. You can see the directory by opening
Edit > Preferences > Folders > Plug-ins.
On Windows, there will usually be two paths that look something like:
C:/Users/USER/AppData/Roaming/GIMP/3.0/plug-ins
C:/Users/USER/AppData/Local/Programs/GIMP 3/lib/gimp/3.0/plug-ins
Either of them of will work.
If you are lazy, you can simply clone this project into the plug-ins
directory.
cd path/to/GIMP/3.0/plug-ins
git clone git@github.com:omgimanerd/gimp-to-minecraft .
This will put the rest of the project crap in the directory though.
Alternatively, you can use the installer script.
cd path/to/GIMP/3.0/plug-ins
curl https://raw.githubusercontent.com/omgimanerd/gimp-minecraft-bridge/refs/heads/gimp-3.0/install.sh | bash
Once you've copied the scripts into your plugins directory, they are available under the Filters menu:
I have them bound to keyboard shortcuts for ease of use, which you can do under
Edit > Keyboard Shortcuts
Invoke the Minecraft to GIMP script on a Minecraft style animated texture
will slice the texture into layers which you can then edit and preview using
GIMP's animation tooling. GIMP to Minecraft does the opposite to stack the
image layers back into the Minecraft animated texture format.
Using AE2's singularity texture as an example, invoking the script on the left
image generates the image on the right, with each frame sliced into layers.
You can then use Filters > Animation > Playback to preview the animation, and
each frame becomes its own separate layer for editing. Once you're done editing
the individual layers, you can use GIMP to Minecraft to convert it back into
the Minecraft format.
