Change Log

1.3.5 2018-11-02

• Improved handling of primitives with different attributes using the same material. Materials are now duplicated. #163
• Fixed a bug where primitives without texture coordinates could use materials containing textures. Those textures are now removed. #163
• Improved parsing of faces with mismatching attributes. #163
• Added ability to use the first material in the mtl file when the obj is missing usemtl. #163
• Fixed handling of unnormalized input normals. #163
• Fixed handling of materials where the diffuse and ambient texture are the same. #163
• Fixed handling of usemtl when appearing before an o or g token. #163
• Fixed loading faces that contain less than 3 vertices. #163
• Attempt to load missing materials and textures from within the same directory as the obj. #163
• Fixed loading mtllib paths that contain spaces. #163
• Improved handling of materials with alpha. If the alpha value is 0.0 it is now treated as 1.0. #164

1.3.4 2018-10-16

• Improved parsing models with concave or n-sided faces. #158
• Fixed handling of objs with interleaved materials. #156

1.3.3 2018-09-19

• Fixed handling of objs with mismatching attribute layouts. #154
• Fixed parsing mtl textures that contain texture map options. #151
• Fixed normalization of Windows paths when running the converter on Linux. #151

1.3.2 2018-06-07

• Fixed greyscale images loading as alpha instead of luminance. #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
• Fixed parsing models with line breaks. #85

1.2.0 2017-07-11

• Change texture sampling to use NEAREST_MIPMAP_LINEAR by default. #83.
• Fixed lighting when generating normals. #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
• Fixed issues with an extra .bin file being saved when using --separate. #62
• Fixed issue where an ambient color of [1, 1, 1] overly brightens the converted model. #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
  • Speed improvements, especially for larger models.
  • Preserves the objects and groups in the obj.
  • Added documentation and tests.
  • Material fixes.
