I want to implement the functions in this video, how should I set the window

It is gone from where I used to find it on Apple’s web site. Is it deprecated or no longer available?

So I am exporting a .usdc file from blender that already has some morph animations. The animations play well in blender but when I export I cannot seem to play them in RealityKit or RCP. Entity.availableAnimations is an empty array. Not of the child objects in the entity hierarchy has an animation library component with it. Maybe I am exporting it wrong but I tried multiple combinations but doesn't seem to work. Here are my export settings in blender The original file I purchased is an FBX file that has the animation but when I try to directly get it in RealityConverter it doesn't seem to play animations.

Goal: To render in an apple vision pro app, the solid-mechanics 3D simulation results coming form an FEA code. Starting point: I have surface vtks with deformations on each node. Each time step has a a mesh with the nodal coordinates. This is straighforward translatable to a usd MeshSequence. Unfortunately, the results cannot be simplified to a scaling o linear transformation as you would do with other game-oriented animations. Tools: Right now, I am using Xcode and reality composer pro (RCP) to build the scenes. Technical limitations: I am aware that RCP can do animations with BlendMesh and skeletons and that MeshSequence is not a problem. Progress: Coverting to the sequence of vtk meshes to a usd MeshSequence is straighforward. This animates correctly in Preview and Blender (see screenshot). I managed to convert from MeshSequence to multiple keys and BlendMesh. This also animates correctly in Blender and preview. Unfortunately, the BlendMesh of multiple blended meshes shows a zero animation time in RCP (see screenshot below) Also, see below usda file scheme for the animation. Of course I am not showing full vectors such as faceVertexCounts, faceVertexIndex, normals. Question: what is the right set up to create a BlendMesh animation that RCP will correctly import and animate, form a set of Meshes or multiple key shapes?

reality Converter Where is the download link? I can't find it

https://developer.apple.com/cn/augmented-reality/tools/. Why is this address missing? Reality Converter, what should we use now to convert the model

The error: When building a RealityKitContent package that contains a USDZ file exported from Blender, Xcode throws the following error: error: [xrsimulator] Exception thrown during compile: Cannot get rkassets content for path .../RealityKitContent.rkassets because 'The file "RealityKitContent.rkassets" couldn't be opened because you don't have permission to view it.' error: Tool exited with code 1 The error message mentions "permission" — but permissions are not the issue. This appears to be a misleading error from realitytool masking a USD validation failure. What I've ruled out File permissions — all files are -rw-r--r--, user has Read & Write on the folder Extended attributes / quarantine flag — other files with the same @ flag work fine Corrupted archive — unzip -t confirms the USDZ is valid (board.usdc + textures) Stale build cache — deleted DerivedData and com.apple.DeveloperTools cache, no change Key observations The same file builds successfully on my colleague's machine running identical Xcode 26.3 - MacOS 26.3 Other USDZ files in the same .rkassets bundle (downloaded from Sketchfab, or created in Reality Composer Pro) compile without any issue. Only USDZ files exported directly from Blender are affected. When the file is placed in Bundle.main and loaded via Entity(named:in:.main), it works perfectly — no errors Reality Converter flags the file with two errors: UsdGeomPointInstancers not allowed, and root layer must be .usdc with no external dependencies The confusing part: the same file compiles fine on an identical Xcode 26.3 setup and importing method. This suggests either a machine-specific difference in Xcode's validation behavior, or a cached .reality bundle on my colleague's machine that isn't being recompiled. Current workaround: Loading from Bundle.main instead of the RealityKitContent package bypasses realitytool entirely and works, but loses Reality Composer Pro integration: if let entity = try? await Entity(named: "test", in: Bundle.main)
