  • Support for animated morph targets / blend shapes
  • Support for sparse accessors (morph targets and vertex positions only for now)
  • Safe build option for more robust loading (GLTFAST_SAFE scripting define)

Changed

  • Minor primitive GameObject name change. GltfImport is now fully responsible for GameObject names in order to ensure consistency between animation paths and model hierarchy.
  • glTF importer inspector
    • Removed "Node Name Method" option from glTF importer inspector. It still an option at run-time, but is always OriginalUnique at design-time imports.
    • Animation setting is disabled if built-in package animation is disabled
  • For better clarity, changed type of Sampler properties minFilter, magFilter, wrapS and wrapT from into to enum types and added tests
  • Optional dependencies

  • Support for two texture coordinate sets in materials (URP, HDRP and Built-in; fixes #34)
  • Support for individual texture transform per texture type (URP, HDRP and Built-in)
  • Support for occlusion maps on specular-glossiness materials (extension KHR_materials_pbrSpecularGlossiness)

Fixed

  • Editor import: Separate textures are only referenced in AssetDatabase (not re-added)
  • Warnings due to conflicting script file names Animation.cs and Camera.cs (#198)

[4.0.1] - 2021-06-10

Changed

  • Renamed GLTFast.ILogger to GLTFast.ICodeLogger to avoid confusion with UnityEngine.ILogger

Fixed

  • Null pointer dereference exception on accessorData (thanks @hybridherbst)
  • Corrected flipped texture transform for KTX texture (#176)

[4.0.0] - 2021-05-21

Added

  • Import glTF files at design-time in the Editor
  • Custom inspector for imported glTF files, featuring import log messages
  • ImportSettings can be provided to GltfImporter.Load (optionally) to customize the loading behaviour (quite limited at the moment, but gives room to grow)
    • ImportSettings.nodeNameMethod to allow customizing Node/GameObject naming convention
  • IGltfReadable interface for GltfImporter
  • Import and instantiation logging customization (see ILogger). Allows users to analyze log messages and/or opt out of logging all messages to the console (which is still done by default if you're using GltfAsset).
  • Scene support. glTF can contain multiple scenes and now it is possible to instantiate them selectively
    • GltfImport.InstantiateMainScene to create an instance of the main scene (or nothing if the scene is not set; following the glTF 2.0 specification)
    • GltfImport.InstantiateScene to create an instance of a specific scene
  • GPU instancing via EXT_mesh_gpu_instancing glTF extension (#107).
  • Camera support (via IInstantiator.AddCamera; #12)

Changed

  • Coordinate space conversion from glTF's right-handed to Unity's left-handed system changed. Please see the upgrade guide for details and the motivation behind it.
  • Nodes' names are made unique (within their hierarchical position) by supplementing a continuous number. This is required for correct animation target lookup and import continuity.
  • IInstantiator.AddPrimitive extended parameter first (bool; true for the first primitive) to primitiveNumeration (int; counting upwards from zero). This allows for creating unique GameObject names.
  • Renamed the main class GltFast to GltfImporter to properly reflect its purpose. There is a fallback GltFast class for backwards compatibility
  • Renamed GltfImporter.Destroy to GltfImporter.Dispose to have more consistent naming similar to native containers
  • IMaterialGenerator overhaul that allows more flexible generation of materials (ahead of time)
    • GenerateMaterial instead of passing on all require data (like full texture arrays), data has to be fetched from the GltfImporter/IGltfReadable.
  • IInstantiator.AddPrimitive: Instead of Material the IDs/indices of materials are provided and the materials themselves have to be fetched from the IGltfReadable/GltfImporter (allowing more flexible usage)
  • GltfImport.InstantiateGltf (instantiates all scenes at once) is marked obsolete in favour of InstantiateMainScene and InstantiateScene
  • Performance improvement: NativeArray buffers are not created copying memory. Instead they are created from pinned managed byte arrays. This should have some positive effect on binary glTFs with Draco meshes and KTX textures.
  • Update to DracoUnity 3.0.0

Removed

  • Compiler errors in Tests assembly due to inconsistent/incomplete class names/namespaces changes

[3.0.0] - 2021-02-04

Changed

  • Moved SampleSet related code into dedicated Assembly, so it can be used in unit tests as well client applications (but doesn't have to).

  • Apply material's occlusion strength properly
  • Removed artifacts on double sided opaque materials
  • Properly clean up volatile download dictionaries
  • Build compilation when targeting URP/HDRP

[2.5.0] - 2020-12-14

Added

  • Ported partial support for transmission materials to URP/HDRP 7.x
  • Improved/alternative transmission mode for Universal Render Pipeline that kicks in if Opaque Texture is enabled in URP settings

[0.11.0] - 2020-03-07

Added

  • Support for texture samplers' wrapping mode
  • Support for texture samplers' filter modes (partial; see issue)

Changed

  • Increased performance due to more balanced threading by making all C# Jobs parallel
  • Refactored loading behavior
    • Main loading class does not interfere with it's IDeferAgent anymore. It just follows its order.
    • GltfAsset now has a loadOnStartup flat to disable automatic loading

Added

  • Support for Universal Windows Platform (not verified/tested myself)

Changed

  • Refactored GltFast class to control loading coroutine in an effort to make usage and future port to async easier.
  • Optimization: Data loading is now based on accessors (rather than primitives). This reduces redundant loading jobs wherever accessors are used across primitives.
  • Optimization: Primitives of a mesh, that share vertex attributes now become sub-meshes of one Unity Mesh. This reduces memory usage and creates less Renderers/GameObjects.
  • glTF type (JSON or binary) is now auto-detected based on file name extension. Removed obsolete GlbAsset. This was done so GltfAsset can be derived off more flexible.

[0.9.0] - 2020-02-02

Added

  • Support for quantized mesh data via KHR_mesh_quantization extension

Changed

  • UV space conversion now happens per UV coordinate (not negatively scaled via texture tiling anymore). This helped to fix tangent calculation.

Fixed

  • Certified correct normal mapping by making normals, UVs and tangents consistent
  • Double sided material fixes

[0.8.1] - 2019-12-05

  • Support for vertex colors in materials
  • Support for implicit/undefined primitive indices

Changed

  • Using custom glTF shaders instead of Unity Standard shaders. This speeds up occlusion and roughness/metallic texture loading since they don't have to be converted at runtime anymore.

Fixed

  • Factor and texture (for metallic-roughness and specular-glossiness) are now multiplied as defined in spec.
  • Unlit materials now support baseColorTexture and texture transforms

[0.7.1] - 2019-11-29
