I want to crop the usdz model in runtime. I use ModelIO for this. Before: [https://i.stack.imgur.com/yDXXF.jpg) After: [https://i.stack.imgur.com/m9ryg.jpg) First of all, get file from bundle let url = URL(fileURLWithPath: file) } else { print("Object not found in Bundle") } And then I need to access asset let asset = MDLAsset(url: url) What should I do after this step? How am I supposed to use SCNGeometrySource and SCNGeometryElement or MDLVoxelArray classes?

I want to remove unnecessary materials or textures in order to reduce the size of the USDZ model I have. How can I manipulate this model with swift? or, I can try any advice to reduce the size of the USDZ model

Can I take photos from an android device or any camera instead of an ipad or iphone while using the Object Capture API? What negative side effects can it have. Note: I'm asking this question because I noticed that the size of the usdz model has grown too much in my experiments. (For example 200mb instead of 20mb)
