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

Table of contents

The purpose

When exporting from Blender in glTF 2.0, save textures as external files instead of embedding them in a single file.

Blender：3.4.1

Access the export dialog by selecting “File” in the upper left corner, then “Export,” and finally “glTF 2.0 (.glb/.gltf)”.

Click the format selection field on the right-hand side of the displayed dialog.

Save as glTF Separate (.gltf + .bin + textures).

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

Example）

3D.gltf
3D.bin
texture.png

Because the image file is saved separately as a 3D file, it can be directly edited with paint software or similar applications.

The 3D.gltf file can also be directly edited.
