We've redesigned CesiumJS's glTF loader! The new architecture makes it easier to add new features like 3D Tiles Next metadata and instancing. @glTF3D

The @playcanvas engine now supports the #glTF extension KHR_materials_iridescence. This means it now has support for 100% of ratified glTF extensions! 🎉
PR is here: github.com/playcanvas/engine…

Siggraph2022では、日本時間8/2 1時にglTFモデルの物理ベースレンダリング（PBR）マテリアルについてのトークがオンライン開催されるようです。
セッションにはglTFの開発元＆規格策定も進めるクロノス・グループのメンバーや、model-viewerを開発するgoogleのエンジニアも登壇予定だそう。
Join us for the "Advanced PBR Material Parameters in glTF" virtual BOF at SIGGRAPH 2022 on Aug 1st at 9am PDT. The material model in glTF has evolved a lot in the past few years. @glTF3D s2022.siggraph.org/presentat…

I'll be there to answer #glTF and rendering questions too; ask me a hard one!

This is the best explanation of UV mapping I have seen so far. One picture > 1000 words.

After nearly two years of fixes, features, and using all of this in production, I finally made The Big Pull Request that will bring the UnityGltf repository back to life:
github.com/KhronosGroup/Unit…
In a nutshell: this makes @unity a very versatile @glTF3D exporter.
