I converted a Wavefront OBJ model to glTF using obj2gltf command-line tool. The converted glTF model has missing geometries. In fact, the converted model has just one rectangular polygon and no other geometries from the original OBJ model. However, when I convert the OBJ to glTF using Cesium ion, the glTF looks complete and fine.
obj2gltf version: 3.1.0
Platform: Windows 10
Node version: 12.14.1
I did not get any error logs from obj2gltf. What could be the potential cause(s) for this issue, when using obj2gltf command-line tool?
Thank you.
