Many thanks for the reply. I have tried linking to the .usdz file directly (I am assuming the file needs to be in the same directory as the project) but on ios it says ‘object could not be opened’. I am using the AR template so is there something else I need to do to it such as deleting any existing objects in the max scene or removing references to objects in the puzzles?
I have attached a screen shot of how I referenced the .usdz file.
Sorry for my ignorance but just trying to get my head around how this all works..
