glTFast 4.8.2

What's New

Changed

glTFast 4.8.1

What's new

Changed

• Bumped Burst dependency version to 1.6.6

Fixed

• UWP build (#400)
• Shader compile errors in 2021.2 and later due to incorrectly named property in legacy shader graph glTF-pbrSpecularGlossiness-Opaque-double

glTFast 4.8.0

Changes

Added

• A target layer can be defined for instantiated GameObjects via GameObjectInstantiator.Settings.layer (thanks @Holo-Krzysztof for #393)
• Re-normalize bone weights (always for design-time import and opt-in at runtime via GLTFAST_SAFE scripting define)
• GltfAssetBase.Dispose for releasing resources

Changed

• Mecanim (non-legacy) is now the default for importing animation clips at design-time (thanks @hybridherbst for #388)
• Mipmaps are generated by default now when importing at design-time (thanks @hybridherbst for #388)
• All four bone weights are imported at design-time, regardless of quality setting
• SkinnedMeshRenderer's rootBone property is now set to the lowest common ancestor node of all joints. This enables future culling optimization (see #301)

Fixed

• Fail more gracefully when parsing invalid JSON
• Proper error handling on glTF-binary files with invalid chunks (unknown type or invalid length; #389)
• Properly handle skins without inverse bind matrices
• Avoid loading Jpeg/PNG textures twice when they are sampled linearly or mipmaps are generated

glTFast 4.7.0

This release is mainly fixes and workflow improvements

Added

• RenderPipelineUtils to detect current render pipeline
• Option to make glTFast an alternative .glb/.gltf importer (not default anymore; via scripting define GLTFAST_FORCE_DEFAULT_IMPORTER_OFF). Useful in projects where you have another default importer for glTF (thanks @hybridherbst for #367)
• Prefabs glTF-StableFramerate and glTF-FastestLoading for easy, no-code setup of global runtime loading behavior (via IDeferAgent)
• GltfImport.SetDefaultDeferAgent and GltfImport.UnsetDefaultDeferAgent for setup of global runtime loading behavior (via IDeferAgent)
• TimeBudgetPerFrameDeferAgent component now has a frameBudget property with a nice slider in the inspector

Changed

• (DOTS) Update to Entities 0.50
• (DOTS) Removed unused GltfComponent
• Bumped Mathematics and Burst package dependency versions to current 2019 LTS verified versions
• Renamed UniveralRPMaterialGenerator to UniversalRPMaterialGenerator (typo)

Fixed

• (Export) Remember destination path when exporting individual GameObjects from menu
• (Export) Vertical texture transform offset is correct now
• Improved relative file path handling on platforms with non-forward slash directory separator (Windows)
• (Import) Draco compressed meshes' submeshes now have bounds set from the accessor's min/max values (just like regular/uncompressed meshes; #384)
• (Export) De-duplication by properly re-using glTF mesh if accessors and materials are identical (#364)
• (Export) Removed error messages about non-matching Profiler calls (#357)
• (Export) Re-encoded (blitted) textures are in correct sRGB color space, even when the project is in linear color space (#353)
• (Export) Removed incorrect color space conversion on normal maps (#346)
• For projects using the built-in render pipeline in gamma color space, vertex colors are now applied in the correct color space

glTFast 4.5.0

This release tackles a couple of material issues in URP/HDRP and simplifies future material extension work.

Upgrade to 4.5.0

New shader graphs are used with certain Universal and High Definition render pipeline versions, so projects that included glTFast's shaders have to check and update their included shaders or shader variant collections (see Materials and Shader Variants for details)).

Changes

Added

• Generic shader graphs (to reduce the amount of shader graphs to maintain and reduce shader variants)
  • glTF-pbrMetallicRoughness
  • glTF-pbrSpecularGlossiness
  • glTF-unlit

Changed

• The new, generic shader graphs are used for
  • Universal render pipe 12 or newer
  • High-Definition render pipe 10 or newer
  • Optional/Experimental for the Built-In render pipe (see Shader Graphs and the Built-In Render Pipeline in the documentatoin for details)

Fixed

• Correct emission in HDRP 12 and later
• (Shader Graph) Vertex color alpha channel is used properly
• (Shader Graph) Correct vertex colors when project uses linear color space
• (Shader Graph) Emission is now in correct color space

glTFast 4.4.11

Changed

• SkinnedMeshRenderer created by the GameObjectInstantiator will have updateWhenOffscreen set to true to avoid culling issues (at a performance cost; #301)
• (Editor Import): Imported Mecanim AnimationClips now have Loop Time set to true (fixes #291)

Fixed

• Improved skin deformation on unorderd-joints-glTFs in projects with Skin Weights (quality setting) below 4 (#294)
• Textures are not duplicated anymore if they reference different samplers with equal settings (yields huge memory savings, depending on some glTFs; thanks Vadim Andriyanov for #304)

glTFast 4.4.10

What's new

Changed

• Improved frame rate when loading glTFs with many morph targets (thanks Eric Beets for #287)
• GameObjectInstantiator.SetNodeName can be overridden now (thanks STUDIO NYX for #297)

Fixed

• Matrix decompose error (thanks weichx)
• Flickering animation on invalid glTFs from Sketchfab (#298)

glTFast 4.4.9

Changes

Fixed

glTFast 4.4.8

Changes

Fixed

• Morph target animation curves have correct first keyframe value now (thanks Eric Beets for #277)
• (URH/HDRP) UV transform and UV channel on blended materials
• Error when using transmission approximation without a logger provided
