Mesh must have normals and uvs

[jst84]

Hi, I use this application to convert dicom files to obj file.
When I try to use it in a 3d application, something goes wrong with this message:
"Mesh must have normals and uvs"

Could you help me/there is any option that can I set on command line?

Thanks a lot,
Stefano.

Hi Stefano,

Do you export the mesh as obj? Something like
dicom2mesh -i xxx/yyy -o myMesh.obj

If that is the case, please try to export the mesh as stl
dicom2mesh -i xxx/yyy -o myMesh.stl
We wrote the obj exporter ourself. It does not export uv coordinates. However, blender and meshlab are able to open our obj. What application do you use'

Hi eidelen, thanks for the quick response.
Yes, I export the mesh as obj and then I use a custom software (something not famous) to view it.
I'm going to talk with the team about the stl format.
Thanks a lot,
Stefano.

Hi Stefano,
Is this issue still active? If not, I suggest to close it. Fine for you?
Thanks, Adrian

Hi Adrian,
yes, you do. I resolved by using a blender script that unwrap the mesh: bpy.ops.uv.cube_project().
Thanks a lot,
Stefano.
