I wanted to create a particle effect using particle images I copied from a Unity project. These images are PNGs with an alpha channel. In Unity, these look georgeous, but on visionOS, they look rather weird, since the alpha channel is not respected. All pixel which are not pitch black are full white. Is there a way to change this behavior?

I’d like to convert a Filemaker 18 Runtime to a Mac (Catalina) application package. I found a youtube video that describes how to convert a shell script into a Mac OSX App. This is the shell script: I’ve had no luck adapting it to convert my Filemaker runtime into an app. Thanks in advance for any advice. Regards, Lara

How to set the scale unit of an Entity in Reality Composer Pro, for example, if the scale value is 1 meter, then when this Entity is placed in RealityView, the displayed size will be 1 meter If the unit of scale cannot be set in Reality Composer Pro, is there a way to specify the unit of scale in the code so that the Entity can be displayed in meters when added to RealityView Thank you

I'm trying to control the LOD of textures for an app for vision pro, With the default image node in composer pro the UV's are correct but the LOD is not what I want, I would like to have control over it. I see there is a node called "RealityKitTexture2DLOD" but as soon as I try to use that one the UV's are all messed up. Am I missing something ? Do we need to do something specific to use this node ? I tried to use the nodes "Place 2D" and "UsdTransform2d" but could not get the texture to align Any help appreciated

As the title says. While I can find the video capture on the desktop but I can not find where it is storing the screenshots even when it says Screenshot's succeeded. I am referencing this: https://developer.apple.com/documentation/visionos/capturing-screenshots-and-video-from-your-apple-vision-pro-for-2d-viewing

I'm taking my iOS/iPadOS app and converting it so it runs on visionOS. I’m trying to compile my app, build it, for both visionOS and iOS. When I try to build for an iPhone and iPad simulator, I get the following error:  Building for 'iphonesimulator', but realitytool only supports [xros, xrsimulator] I’m thinking I might need to do a # if conditional compilation statement for visionOS so iOS doesn’t try to build lines of code but I can’t for this particular error find out for which file or code I need to do the conditional compilation. Anyone know how to get rid of this error? 

I created an app for visionOS, using Reality Composer Pro. Now I want to turn this app into a multi-platform app for iOS as well. RCP files are not supported on iOS, however. So I tried to use the "old" Reality Composer instead, but that doesn't seem to work either. Xcode 15 does not include it anymore, and I read online that files created with Xcode 14's Reality Composer cannot be included in Xcode 15 files. Also, Xcode 14 does not run on my M3 Mac with Sonoma. That's a bummer. What is the recommended way to include 3D content in apps that support visionOS AND iOS?! (I also read that a solution might be using USDZ for both. But how would that workflow look like? Are there samples out there that support both platforms? Please note that I want to setup the anchors myself, using code. I just need the composing tool to the create 3D content that will be placed on these anchors.)

Hi, Is there a way to access the shader graph nodes in Xcode to change the values during runtime such as changing values based on user inputs? Or is this not possible yet? Thanks! Myoung

I made an animation in Blender using geometry nodes that I exported to USDC file (then I used Reality Converter to convert to USDZ) and I can see the animation when viewing from the finder but does not play after importing to RCP. Any idea how I can play the animation? Or can the animation be accessed through Xcode? Thanks!

getting this error in the apple vision pro

Session 10166 goes into wonderful detail about the construction of spatial photos, and the various parameters that define the relationship between left and right images. The session provides everything I need to know to combine a left and right frame, and create a spatial image output. But I'd like to do a live preview on the Vision Pro. Change the baseline and see what it looks like. See the horizontal disparity/convergence adjustment and move the image back and forth. Cropping, and vertical alignment, would be easy to implement live. Horizontal disparity, and baseline length? I'm baffled. How would I create a Shader Graph to let me make these adjustments using sliders or similar affordances, and pipe the results to a Camera Index Switch? I already have a working stereography app, but the stereo parameters are not interactive at all. I could regenerate the spatial image after each change and refresh the display, but that is awfully clunky. What's a better way?

Hey guys! I have question for my project. I want my 3D character with an PBR Shader to only receive IBL from my HDRI map and not receive any lighting from the surrounding environment when viewing on Apple Vision Pro. Any tips? Thank you in advance!

We deliver an SDK that enables rich spatial computing experiences. We want to enable our customers to develop apps using Swift or RealityComposer Pro. Composer allows the creation of custom components from the add components button in the inspector panel. These source files are dropped into the RealityComposer package and directory. We would like to be able to have our customers import our SDK components into their applications RealityComposer package and have our components be visible to be applied by our customer into their scene compositions. How can we achieve this? We believe this will lead to a risk ecosystem components extensions for RealityComposer Pro.

I saw onnoffitacation in the Behavior configuration of Reality Composer pro, which asked me to enter the Nofficatition name, that is to say, this requires swift in Xcode to send a message. There is a message name in the message, so I hope you can write an list for me how to use Swift in Xcode to send a message containing the message name.

With WWDC 24, I was excited to see that apple is bringing their APIs from Vision OS to iOS. I tried using the Object Anchoring component in Reality Composer Pro. Which this works with a Vision Pro, it looks like the entity will spawn at origin if we run the same on iOS and the object anchoring doesn't seem to work. Is this intended? Below is how I'm doing this. I added an Anchoring component and added the .referenceObject file I trained using CreateML. This is the code I'm using to load this scene in. // GrootView.swift // ARTest-New // // Created by Sravan Karuturi on 6/10/24. // import SwiftUI import RealityKit import Box struct GrootView: View { @StateObject private var grootVM = GrootViewModel() @State private var ent: Entity? = nil @State var anchor: Entity? = nil @State var wallAnchor: Entity? = nil @State var floorAnchor: Entity? = nil var body: some View { RealityView{ content in #if os(iOS) await content.setupWorldTracking() content.camera = .worldTracking #endif ent = try? await Entity(named: "Box", in: boxBundle) print(ent?.children) anchor = ent?.findEntity(named: "ObjectAnchor") wallAnchor = ent?.findEntity(named: "WallAnchor") floorAnchor = ent?.findEntity(named: "FloorAnchor") let updateSum = content.subscribe(to: SceneEvents.Update.self){ event in if let anc = anchor, anc.isAnchored { print("Found Item") } if let anc = floorAnchor, anc.isAnchored { print("Found Floor") } if let anc = wallAnchor, anc.isAnchored { print("Wall Anchor") } } content.add(ent!) } } } #Preview { GrootView() } While, something similar seems to work on visionOS, the same doesn't seem to work with iOS. When I run this app, we see all the children and the Found Item is printed constantly even when we don't have the item in the scene. Not really sure if this is just not supported yet on iOS ( I really hope that's not the case ) or if I messed up something somehow

Is there a way to make a SpatialAudio object autoplay its assigned track strictly via settings in Reality Composer Pro, no Swift code involved?

Hello just getting this error as I am trying to run the any new project this error is looking up Thanks Zipzy Games X

this week i was watching https://developer.apple.com/videos/play/wwdc2024/10105/ with the amazing "configuration" feature to change the color or mesh straight in quick look, but i tried a lot with goarounds but nothing bring me to success how do i write in the usda files? anytiome i overwrite the usda even with just a "{}" inside... Reality composer pro rejects the file to be open again where is the developer man in the tutorial writing the usda? how is the usda compressed in usdz? (none of the compressors i tried accepeted the modified usda file) this is the code it's suggested in the video #usda 1.0 ( defaultPrim = "iPhone" ) def Xform "iPhone" ( variants = { string Color = "Black_Titanium" } prepend variantSets = ["Color"] ) { variantSet "Color" = { "Black_Titanium" { } "Blue_Titanium" { } "Natural_Titanium" { } "White_Titanium" { } } } but i dont understand how to do it with my own files,

HI eveyone i've read that USDZ supports LOD to have 3 meshes with high medium and low polygon detail to be visible depending on the distance from the user to the entity... but i dont know how to use it... any experience or... god bless you... a downloadable file with a sample??? thanks a lot !!!!

hello i wanna play mp4 file in VideoMaterial avPlayer. so first i make to use reality composer pro. I created matterial using the sphere provided by default in Reality Composer Pro and exported it to usdz. and when i play mp4 file in sphere matterial, it's good play But i wanna custom created matterial (ex. shaper3d create 3d modeling) not good play. i make custom created matterial - it's curved matterial curved matterial in shaper3d and exported it to usdz. curved matterial in Reality Composer Pro Scene and exported it to usdz. when i play mp4 file in curved matterial, it's not good play -> not adjust screen play How can I adjust and display the video in a custom usda file?
