I have tried to prevent a user from changing the scale of a 3d model in AR Quick Look. I have used allowsContentScaling as described here: https://developer.apple.com/forums/thread/124558?answerId=389784022#389784022

My code look something like that:

<a rel="ar"
href="https://developer.apple.com/augmented-reality/quick-look/models/drummertoy/toy_drummer.usdz#allowsContentScaling=0 ">
Open AR</a>

Unfrotunettley it didn't work. I can still resize a model.
Am I doing something wrong?

Hi MankaM,

Looking at the code you provided, it seems to be missing an img or picture element, which Safari requires to decorate the preview with an AR badge and allows the model to be previewed directly inline instead of first navigating to the file.

This code should respect the content scaling option:

Code Block <a rel="ar" 
	 href="https://developer.apple.com/augmented-reality/quick-look/models/drummertoy/toy_drummer.usdz#allowsContentScaling=0 ">
	 <img src="https://developer.apple.com/augmented-reality/quick-look/models/drummertoy/drummertoy_2x.jpg">
</a>
