Indices of point and line meshes are mixed up after compression

[rhonke]

Hi, I'm facing issues with lines and points after compression, so I have posted an issue in the library for which MeshOptimizerWrapper is a wrapper.

zeux/meshoptimizer#993

Here is the issue:

When compressing files that contain lines or points, their indices are mixed up.

Before compression:

After compression:

It seems this is independent of any setting. I think this library assumes that there are always three indices because a "mesh" consists of triangles. But Gltf also knows lines and points.

It seems this may be solvable by referencing another version of the MeshOptimizer.
Please see the conversation in the linked issue for which version to take.
