Saving textures as external files when saving a glTF file (Blender)

Things I want to do

When exporting from Blender as glTF 2.0, save the textures as an external file instead of a single file.

Blender：3.4.1

To display the export dialog, go to ‘File’ in the upper left corner → ‘Export’ → glTF 2.0 (.glb/.gltf).

Click the format button on the right side of the dialog box that appears.

Select glTF Separate (.gltf + .bin + texture) and save.

The specified filename.gltf, specified filename.bin, and texture files (image files) will be saved in the selected folder.

example)

3D.gltf
3D.bin
texture.png

Since the image file is saved separately as a 3D file, it can be directly edited using paint software or similar programs.

You can also edit 3D.glt directly.
