I wanted to show a progress of a certain part of the game using an entity that looks like a "pie chart", basically cylinder with a cut-out. And as progress is changed (0-100) the entity would be fuller. Is there a way to create this kind of model entity? I know there are ways to animated entities, warp them between meshes, but I was wondering if somebody knows how to achieve it in a simplest way possible? Maybe some kind of custom shader that would just change how the material is rendered? I do not need its physics body, just to show it. I know how to do it in UIKit and classic 2d UI Apple frameworks but here working with model entities it gets a bit tricky for me. Here is example of how it would look, examples are in 2d but you can imagine it being 3d cylinders with a cut-out. Thank you!

Hi! I have a new game and I have setup the leaderboards and achievements in App Store Connect but all of them are "not live" and in console I see this warning: "No AchievementDescription could be found for Achievement with ID: {my_ID}" I did not do a fresh Game Center setup for a long time, but is there any way to test if achievements and leaderboards are working for nonreleased game? Thank you!

I started adding GameCenter support for my visionOS game and I noticed an issue. After authenticating the player the access point shows in the location I specified but my window content gets an overlay and game cannot be used. Anybody has experience with GameCenter on visionOS and how to properly set it up and use the GKAccessPoint? Thank you! Adding a screenshot:

Hi! I am making an app where I have a scene with main entity in immersive space. Since my entity is fixed in space I added a reposition entity that allows users to reposition the whole entity in space. I use the drag gesture and translation to move the whole entity in x, y and z coordinates. I wanted to implement the same behaviour that we have when we drag the window bar in visionOS windows. I tried using basic trigonometry and calculate entity rotation and translation relative to the movement but I am not getting the same movement and rotation as in visionOS windows. Does anybody have a working solution for this? I would appreaciate it a lot. :)

I have an iOS app that uses (camera) video feed and applies CoreImage filters to simulate a specific real world effect (for educational purposes). Now I wanted to make a similar app for visionOS and apply the same CoreImage filters to the content (live view) users sees while wearing Apple Vision Pro headset. Is there a way to do it with current APIs and what would you recommend? I saw that we cannot get video feed from camera(s), is there a way to do it with ARKit and applying the filters somehow using that? I know visionOS is a young/fresh platform but any help would be great! Thank you!
