- By default, our demo can export a .obj mesh with vertex colors or a .glb mesh.
- If you select "texture mapping," it will export a .obj mesh with a texture map or a .glb mesh.
- If you select "render GIF," it will export a GIF image rendering of the .glb file.
- If the result is unsatisfactory, please try a different seed value (Default: 0).
