Key creation failed with error "not all meshes are volumes!"

[MarcoDjallo]

Hello !

As the title says, I get the error "not all meshes are volumes!" when trying to generate the 3d model, and I don't undestrand what can I do to solve it.

Anyway I can help troubleshooting the issue?

Windows 10, Python 3.13

Thanks!

At first it didn't recognize a key, I loaded another photo, then it gave me an error - "Failed to process the key: No available triangulation engine!"

they seem 2 different errors but let me check I'll upload some tests also I'm still collecting samples (photos etc) to verify

I’m encountering the same error. Is there any available solution or workaround?

The triangulation engine has to do with an underlying dependency being missing (triangle, pip install triangle fixes that), but then I get a different error: "invalid shapely polygon passed"

python --version Python 3.11.2
not all meshes are volumes
no fix yet

pip install mapbox-earcut manifold3d triangle
fixed the original issue
of triangulation engine
