Model texture changes on Quick-look

[tachnazarov]

Description

The model look as expected when viewing on browser but when I place the model in AR, the model looks so different. It happens for some models, while most of them are showing properly. PLease see example in glitch and screenshots:

Our on-the-fly USDZ conversion is not perfect. For any models that you find to look significantly different in Quick Look, I'd recommend finding another tool to generate USDZ and then serve it separately as the ios-src. Keep in mind that AR will tend to look a bit different anyway since it uses different (estimated) lighting.

Speaking of rendering inconsistency @grorg, we get a lot like this where we can't reliably convert a glTF to a USDZ and retain the rendered look. This is why having a universally-supported format is so important, and why glTF is called the JPEG of 3D.
