Change Log

3.2.0 - 2023-??-??

  • Added doubleSidedMaterial option to force materials to be rendered double sided. #294
  • Strip file paths of any enclosing double-quotes to allow the mtl/texture files to be properly parsed #297

3.1.6 - 2023-02-10

  • Update npm module dependencies.

3.1.5 - 2023-01-25

  • Fixed crash when writing GLB files above 2GB. #280

3.1.4 - 2021-10-15

  • Unlocked CesiumJS package now that CesiumJS 1.86.1 is released with a fix for Node 16. #270

3.1.3 - 2021-09-15

  • Fixed bug where missing .mtl files were no longer being handled gracefully in Node 16. #268
  • Fixed parsing models with tab separated elements like those exported from Tinkercad. #259
  • Locked CesiumJS to 1.84.0 to prevent "ReferenceError: Blob is not defined" error when running obj2gltf.

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

3.1.1 - 2021-06-22

  • Fixed security warnings by updating outdated npm dependencies. #254

3.1.0 - 2020-03-13

  • Added back inputUpAxis and outputUpAxis. #211
  • Fixed handling of mtl and texture absolute paths. #219
  • Fixed specular image not being decoded when referenced by other textures. #217
  • Fixed parsing faces that reference non-existing attributes. #218

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.

0.1.0 - 2016-07-20

  • Initial release.
