Description

This model tests UsdTransform2d texture transform capabilities.

It's a conversion from the glTF test asset with the same name found here: https://github.com/KhronosGroup/glTF-Sample-Models/blob/master/2.0/TextureTransformTest/README.md.

Specification: https://graphics.pixar.com/usd/release/spec_usdpreviewsurface.html#transform2d

Problem: UsdTransform2d not supported

Blender 3.1

Problem: Incorrect order of operations

The specification states that the order of operations is always defined as

result = in * scale * rotate * translation

A different interpretation will lead to incorrect results.
