### 2.1.0 - 2017-12-28

- Fixed loading faces that contain less than 3 vertices. [#120](https://github.com/CesiumGS/obj2gltf/pull/120)
- Attempt to load missing materials and textures from within the same directory as the obj. [#117](https://github.com/CesiumGS/obj2gltf/pull/117)
- Fixed loading mtllib paths that contain spaces. [#116](https://github.com/CesiumGS/obj2gltf/pull/116)
- Fixed checking for transparency when the diffuse texture is used in another texture slot. [#115](https://github.com/CesiumGS/obj2gltf/pull/115)
- Fixed parsing mtl textures that contain texture map options. [#109](https://github.com/CesiumGS/obj2gltf/pull/109)
- Added back support for the `CONSTANT` technique when a model uses the `KHR_materials_common` extension and has no normals. [#108](https://github.com/CesiumGS/obj2gltf/pull/108)
- Improved handling of materials with alpha. If the alpha value is 0.0 it is now treated as 1.0. [#107](https://github.com/CesiumGS/obj2gltf/pull/107)

### 2.0.0 - 2017-08-11

- Breaking changes
  - Obj models now convert to glTF 2.0. Possible material profiles are `metallicRoughness`, `specGlossiness` (using the `KHR_materials_pbrSpecularGlossiness` extension), and `materialsCommon` (using the `KHR_materials_common` extension).
  - Removed `gltf-pipeline` dependency. The following options have been removed: `compress`, `optimize`, `generateNormals`, `optimizeForCesium`, `ao`, and `bypassPipeline`.
  - Removed `inputUpAxis` and `outputUpAxis`. This stage will be incorporated into `gltf-pipeline` instead.
  - `obj2gltf` no longer takes a `gltfPath` argument and saves a glTF file. Instead it returns a promise that resolves to the glTF JSON or glb buffer.

### 1.3.0 - 2017-08-11

- Fixed parsing models with concave or n-sided faces. [#85](https://github.com/CesiumGS/obj2gltf/pull/85)

### 1.2.0 - 2017-07-11

- Change texture sampling to use `NEAREST_MIPMAP_LINEAR` by default. [#83](https://github.com/CesiumGS/obj2gltf/pull/83).
- Fixed lighting when generating normals. [#89](https://github.com/CesiumGS/obj2gltf/pull/89)

### 1.1.1 - 2017-04-25

- Fixed `CHANGES.md` formatting.

### 1.1.0 - 2017-04-25

- Added ability to convert the up-axis of the obj model. [#68](https://github.com/CesiumGS/obj2gltf/pull/68)
- Fixed issues with an extra .bin file being saved when using `--separate`. [#62](https://github.com/CesiumGS/obj2gltf/pull/62)
- Fixed issue where an ambient color of `[1, 1, 1]` overly brightens the converted model. [#70](https://github.com/CesiumGS/obj2gltf/pull/70)

### 1.0.0 - 2017-04-13

- Breaking changes
  - To use `obj2gltf` as a library, call `require('obj2gltf')(input, output, options)`. The previous calling code was `require('obj2gltf').convert(input, output, options)`.
  - Many library options and command-line parameters have been renamed.
- Project cleanup. [#49](https://github.com/CesiumGS/obj2gltf/pull/49)
  - Speed improvements, especially for larger models.
  - Preserves the objects and groups in the obj.
  - Added documentation and tests.

- Update gltf-pipeline to 0.1.0-alpha9
- Added command to generate documentation (npm run jsdoc)

### 0.1.6 - 2016-09-07

### 0.1.5 - 2016-08-26

- Fixed incorrect parameter to the gltf-pipeline.

### 0.1.4 - 2016-08-25

- Added compression flag for quantizing positions, compressing texture coordinates, and oct-encoding normals.

### 0.1.3 - 2016-08-08

- Fixed a bug causing models with no mtl file to not convert.

### 0.1.2 - 2016-07-25

- Converted the API to now use promises instead of callbacks. [#21](https://github.com/CesiumGS/OBJ2GLTF/pull/21)
- Added the ability to optimize the converted glTF for CesiumJS by using the sun as a default light source.

### 0.1.1 - 2016-07-21

- Updated to use gltf-pipeline 0.1.0-alpha2.

### 0.1.0 - 2016-07-20

- Initial release.
