==========

### 1.3.5 2018-11-02

* 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)
* 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 handling of unnormalized input normals. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
* Fixed handling of materials where the diffuse and ambient texture are the same. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
* Fixed handling of `usemtl` when appearing before an `o` or `g` token. [#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)
* Attempt to load missing materials and textures from within the same directory as the obj. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
* Fixed loading mtllib paths that contain spaces. [#163](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/163)
* Improved handling of materials with alpha. If the alpha value is 0.0 it is now treated as 1.0. [#164](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/164)

### 1.3.4 2018-10-16

* Improved parsing models with concave or n-sided faces. [#158](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/158)
* Fixed handling of objs with interleaved materials. [#156](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/156)

### 1.3.3 2018-09-19

* Fixed handling of objs with mismatching attribute layouts. [#154](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/154)
* Fixed parsing mtl textures that contain texture map options. [#151](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/151)
* Fixed normalization of Windows paths when running the converter on Linux. [#151](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/151)

### 1.3.2 2018-06-07
* Fixed greyscale images loading as alpha instead of luminance. [#144](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/144)

### 1.3.1 2018-03-28
* Maintenance release to update major version Node dependencies.

### 1.3.0 2017-08-11
* Fixed parsing models with concave or n-sided faces. [#85](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/85)
* Fixed parsing models with line breaks. [#85](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/85)

### 1.2.0 2017-07-11

* Change texture sampling to use `NEAREST_MIPMAP_LINEAR` by default. [#83](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/83).
* Fixed lighting when generating normals. [#89](https://github.com/AnalyticalGraphicsInc/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/AnalyticalGraphicsInc/obj2gltf/pull/68)
* Fixed issues with an extra .bin file being saved when using `--separate`. [#62](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/62)
* Fixed issue where an ambient color of `[1, 1, 1]` overly brightens the converted model. [#70](https://github.com/AnalyticalGraphicsInc/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/AnalyticalGraphicsInc/obj2gltf/pull/49)
    * Speed improvements, especially for larger models.
    * Preserves the objects and groups in the obj.
    * Added documentation and tests.
    * Material fixes.

### 0.1.7 2017-01-06
