Hello, I'm trying to use AR technology and it's a good way to display our product.However, due to company's policy, we can't allow customers to download our 3D model fiels, nor share them to social media. We find it hard to hide the share button on a QLPreviewController, and I hope you can support that.The second issue I encounter is that I cannot set the transparency of the 3d object. It was describe in WWDC https://developer.apple.com/videos/play/wwdc2018/237/ but there is no way to figure it out.
