GLTFExport error : unsupported 2d coordinates for the geometry position

[ogrergo]

The gltf validator raise a MESH_PRIMITIVE_ATTRIBUTES_ACCESSOR_INVALID_FORMAT for each text primitve.

I was able to export it after adding a 0 z-coordinate for each position.
Maybe add an option flag to make the geometry buffer serializable ? (use Vec3 instead of Vec2 ?)

Are you using THREE.GLTFExporter here? Note that while the geometry could be made serializable, the shader cannot be exported to glTF.
