* Improved handling of primitives with different attributes using the same material. Materials are now duplicated. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
* Fixed a bug where primitives without texture coordinates could use materials containing textures. Those textures are now removed. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
* Improved parsing of faces with mismatching attributes. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
* Fixed handling of unnormalized input normals. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
* Added ability to use the first material in the mtl file when the obj is missing `usemtl`. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
* Fixed loading faces that contain less than 3 vertices. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
