I have a glb model that is loading absolutely fine, repeatedly, in safari or chrome. There is only one texture that is 8192x8192 it never has a problem when loading in browser. when we embed the url into an app, the model loads the first few times (exiting the model and going back to the main menu and then reloading the model) but, after a few attempts, the texture fails to load. The model and all data is visible but the texture, itself, is black. why could this be happening? Is there something in the iOS code that is breaking it? Is the iOS code trying to automatically cache the texture and it’s running out of memory? anyone who can provide the help and support that we require will be much appreciated. thank you advance.

Hi Developers. I need to try to embed GeoData into a USDZ model and then have the capabilities to "explore" the model while walking around in the real world. e.g. load and display a 3D model of Time Square and show a location pin which displays a users' virtual position on the model... when the user walks 10 meters north, in the real world, the location pin must move 10m (to scale) on the displayed model. As a new developer, I'm starting from scratch so would benefit greatly from having my hand held - please don't be afraid of patronizing me. Step 1 - load and display the 3D model Step 2 - geolocate the user Step 3 - translate the user's current position into a position on the 3D model and represent their "position" on the model with a traditional GPS location marker "pin". Step 4 - move the user's GPS pin on the mode, relative to (and reflecting) their actual real world movement. Is this acheivable or have I explained things to ambiguously? I look forward to hearing from my savior(s) as soon as convenient. Thank you in advance
