Hello When processing an ARPlaneAnchor geometry using its ARPlaneGeometry, the triangleIndices is an array of Int16. It's supposed to be an index buffer, which can only be uint16 or uint32 metal. What am I supposed to do with negative indices ? Negative indices are rare but do appear sometimes.

Thank you

Hello @afresse,

I would not expect the indices to be negative. Do you have a reproducible case? If so I think this would make a great feedback report.

If you do end up posting a feedback please post that number here.

Thanks!
