Wrong AR RoughnessMetalness Tiling

[MastaMan]

This is tiling of metallic roughness for PC

This is tiling for iPhone AR mode

Tiling looks very different!

I think the tiling node doesnt get auto converted for usdz. Since the texture is tilable you should be able to increase/decrease the UV map while keeping the tiling 1x1 and get the same effect.

Thanks for your answer. Yep it's an option. But why in viewer it works in AR - not?

Because you are viewing from iPhone, iOS uses usdz model for src instead of the glb/gltf. There is autoconversion from glb to usdz but it doesnt account for the tiling node, so when the model is converted instead of applying the tiling you had in the node it just sets the tiling to 1x1. Did you test on an Android device? I think this is just for autoconverted usdz models, you can always try manually generateing a usdz with the correct specifications and use it for the ios-src="" if that works for you.

To prevent AO and roughness from being combined into one ORM texture, ensure they have different resolutions
