Hi everyone! For some reason my .gltf file couldn’t load even though I installed panda3d-gltf

here is the full traceback:

If anyone can help it would be great!

Thank you🙏

The error message is fairly clear:

No such file or directory: ‘/Developer/Panda3D/models/scene.bin’

The scene.gltf file references a scene.bin file, which should have come with the model, but you have not copied it to the models folder alongside the scene.gltf file.

Ok so I dragged the scene.bin file and it still didn’t work, I then tried also dragging the textures folder and that also did not work. What should I do?

Did you receive the same error message when you dragged scene.bin into the same folder? If not, what error message did you get?

Do you know how I can fix this?

Thanks!

This may be a bug in panda3d-gltf. Please post the model (including the .bin file) and error message on the issue tracker for panda3d-gltf:

Are you sure it’s not something with the code or installation? Not trying to sound like a know it all or something, I’m just curious as I myself might be the problem and not the package.

Can somebody please help me fix the error?
