Texture issues on IOS

šŸŒµ Needle Engine

I have more than one material because I have parts to run the animation on Android.
But none of the materials have an occlusion map

Now for IOS just try a different standing pose than the T pose and of course that the material is displayed correctly.

Iā€™ll be back in the office end of the week and can take a look at your project - weā€™ll figure it out!

Thanks for the additional info

Great Thank you, and and congratulations on the hackathon victory :wink:

We managed it, it was because variables were used in the material in blender. Something must have gone wrong with the export.

Thanks for the update, that is very strange ā€“
so youā€™re saying in both of these cases the model looked correct in Unity but then looked different in Needle ?

This is indeed a bug in iOS QuickLook (RealityKit on Appleā€™s side) ā€“ Iā€™m checking if we can work around it but not sure yet. It does not happen in SceneKit (their other USD implementation). Iā€™ll report a bug nonetheless

51

Yes, exactly. Everything looks good in Unity, even on IOS and Android smartphones in the browser, but no longer in IOS when you click on the AR button.

I may have found a workaround; still looking into it

So the issue is that the mesh is double sided and QuickLook doesnā€™t really support that ā€“ in the next version it will be fixed, but in the meantime you can just set the material to not be double sided (use ā€œRenderFace: Frontā€ instead of ā€œRenderFace: Bothā€)
