Empty output with a specific .3mf file

[bepstein111]

Describe the bug When I open f3d to view any 3mf file, all I see is a gray background, the file name, and the XYZ compass:

To Reproduce Steps to reproduce the behavior:

1. Open the file using f3d [--verbose] example.3mf
2. See nothing

Expected behavior The object(s) from the file appear in the window.

System Information:

• OS: Debian 12 / KDE
• GPU and GPU driver: NVIDIA 3070Ti driver version 535.183.01

F3D Information Paste the content of f3d --version: F3D 2.5.0

Thanks in advance for taking the time to help me out

[mwestphal]

Can you share a non-fonctioning .3mf file ?

it works fine here with this: gears.zip

[bepstein111]

I'd assumed it was something on my end, so I think it'll work fine for you, but maybe not. AMSLitePTFEAdapterPC04-M4.zip

[mwestphal]

I confirm this file is being read by F3D as an basically empty file:

This is probably caused by an assimp issue

[snoyer]

This is probably caused by an assimp issue

Using assimp export to convert to glTF produces a file with the same 3 nodes F3D reports (3MF root with 2 children: Object_2 and Object_3) but no data (no meshes, data buffer of length 0)
