I have a 3d model with UDIMs that I would like to convert to USDZ but not sure if there is support in Reality Converter although the documentation implies you can load up to 6 2k files - unless I have misunderstood this... https://developer.apple.com/documentation/arkit/adding_visual_effects_in_ar_quick_look_and_realitykit (in the Control Texture Memory paragraph) If this right then how do you use Reality Converter to import multiple maps into a given texture field (eg. diffuse) or are there required steps/formats when exporting from Blender Any help would be greatly appreciated

Is there an easy way to disable Ground shadows when viewing my 3D model on the iPhone (in Object view only - I would still like them in AR View) - This would be very handy to have as an option in Reality Converter. I found this article... https://developer.apple.com/documentation/RealityKit/ARView/RenderOptions-swift.struct/disableGroundingShadows ...but have no idea how to implement it since I'm only using Blender and Reality Converter to get the resulting USDZ models via airdrop to my phone. Do I need Xcode?? I really appreciate any assistance anyone can give here

Just updated to Monterey 12.3 and Reality Converter shows error message when dragging and dropping obj (it worked fine before in 12.2.1) Any help would be greatly appreciated
