glTFast 6.7.0

Added

• (Import) Support for materials variants extension.
• Serialization support for material extensions IOR, Sheen and Specular.
• (Import) Ability to load a glTF from a generic Stream (GltfImport.LoadStream; thanks @sandr01d for #10).

Changed

• (Import) Prefabs imported from glTF assets (at design-time) don't have the glTF logo icon assigned to them anymore. This makes it more consistent with other file types (like FBX; fixes #557).

Deprecated

• MetaMaterialExport. Always use MaterialExport.GetDefaultMaterialExport to get the correct material export.

Fixed

• (Export) glTFast shader based materials and textures are exported correctly when using the default render pipeline.
• Added missing entries to the API documentation.
• (Export) Base colors are now in correct, linear color space.
• Alpha mode blend now works as expected in HDRP 11 and newer as well (fixes #699).
• (Export) Fixed mesh min/max when using Draco compression.
