Change Log

3.2.0 - 2025-11-19

• Fixed bug where missing .mtl files were no longer being handled gracefully in Node 16. #268

3.1.2 - 2021-08-02

• Removed minFilter and magFilter from generated samplers so that runtime engines can use their preferred texture filtering. #240
• Triangle winding order sanitization is longer done by default. Use the --triangle-winding-order-sanitization option. #236

3.0.4 - 2019-07-22

• No longer printing texture decode warning if the diffuse and alpha textures are the same. #205

3.0.3 - 2019-06-26

• Fixed parsing of negative face indices. #191

3.0.2 - 2019-03-21

• Fixed a crash when saving separate resources that would exceed the Node buffer size limit. #173

3.0.1 - 2019-03-08

• Fixed handling of materials that don't have names. #173

3.0.0 - 2018-12-05

• Breaking changes
  • The --materialsCommon flag has been removed. Use --unlit instead which uses the KHR_materials_unlit extension. #152

2.3.2 - 2018-11-02

• Improved handling of primitives with different attributes using the same material. Materials are now duplicated. #162
• Fixed a bug where primitives without texture coordinates could use materials containing textures. Those textures are now removed. #162
• Improved parsing of faces with mismatching attributes. #161

2.3.1 - 2018-10-16

• Improved parsing models with concave or n-sided faces. #157
• Fixed handling of objs with interleaved materials. #155

2.3.0 - 2018-09-19

• Fixed handling of objs with mismatching attribute layouts. #153
• Fixed normalization of Windows paths when running the converter on Linux. #150
• Added ability to use the first material in the mtl file when the obj is missing usemtl. #133
• Fixed handling of unnormalized input normals. #136

2.2.0 - 2018-01-29

• Fixed handling of materials where the diffuse and ambient texture are the same. #127
• Added ability to load alpha textures. #124
• Fixed handling of usemtl when appearing before an o or g token. #123
• Fixed output name when running from the command line. #126

2.1.0 - 2017-12-28

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