glTF Models for E-Commerce
I made these assets while contributing to web 3D standards in weekly conference calls with The Khronos Group via their 3D Formats and 3D Commerce working groups.

I also wrote tutorials and guides that feature these assets: Adding Material Extensions to glTF Models and the KTX Artist Guide.
