问题
After download everything from backend (textures, environment, 3D object) into the app, I created a new SCNScene programmatically, with all this stuff.
It works perfectly on all devices, but on iPhones XR, XS and XS Max the textures of those models, that need environment image appear black. As if "None" environment was set.
I can't post code nor images, it's not my project. I'd just like to know if anyone has experienced any problems of this kind, with iPhone XR, XS or XS Max and ARKit.
It's strange that it doesn't happen on other devices.
Thanks.
EDIT 1:
Here is the trace of the error, I'll try to post more info about the project soon.

This is an Apple bug, happens when the resolution of the environment image of the scene is too large. Resizing the environment image of the scene to 1000x500 solves the problem.
