In tests you can use ! liberally, since if you're wrong, the test will fail.

Then you won't have to keep doing it over and over down below.

You marked this as resolved, but I don't think you made the change?

Looking good, just some coding style left.

Sorry, I missed some things last time.

check alt text and ranges - e.g. offset should start at 0, rotation to go to pi, etc.

What do you think of using 3.14 as PI here?

prefer == null for null checks, since truthiness can be surprising.

You need to define Vector2 in the docs.

Check if this is still necessary with the textureCube (since this is the glTF default already).

It does work without it, but might be a good idea to leave it as an example

It's important for the examples to be as simple as possible, and enum numbers like that are confusing. We can answer something like this in a discussion if it comes up.
| x: offsetSlider.value, | ||
| y: -offsetSlider.value | ||
| }; | ||
| material.pbrMetallicRoughness['baseColorTexture'].texture.sampler.setOffset(offset); |

Let's save this sampler as a const up above so we can simplify these example functions.
* Get and Set texture transform * Adds feature google#3368 * Adds modelviewer.dev example * Texture Transform in Sampler * constructor fix * Sampler API working Missing automated test * Add test * Document and clean gltf file. * Revoke url from test * Remove test.only * Fix coding style. * Clean index and test file
