Export glft error from paraview

simple_model.vtk (175.9 KB)
I tried to export the above model from Paraview to gltf model. I didn’t use any filter, just changed the color to color by Material.

But the model exported cannot be opened by the windows 3D viewer which can view gltf model. Then I used an online viewer, the model is strange as follows and an error was given. Please help, thanks!

Indeed, looks like there is an issue with Cell Data export. You can use CellDataToPointData before export to fix this. But please open an issue on our bug tracker: https://gitlab.kitware.com/paraview/paraview/-/issues
