SCNSceneSource identifiers with usdz file are empty
We are working on a project with ARKit 2 + SceneKit, iOS 12.
We were able to retrieve CAAnimation
instances with .dae
files and control them at runtime.
Now, we are trying .usdz
, but none of the classes can be extracted from SCNSceneSource
with usdz :
let source = SCNSceneSource(url: url, options: options)
let animationIdentifiers = source?.identifiersOfEntries(withClass: CAAnimation.self)
animationIdentifiers
is always empty. The same goes for all classes listed in the documentation for this function https://developer.apple.com/documentation/scenekit/scnscenesource/1523656-identifiersofentries
We have tested our own usdz creations as well as some usdz from https://fusionar.app.
Tough, the animations play nicely when viewing the file either on iOS or in Xcode, where we have access to the animations and scene graph settings :
But definitely not from code at runtime, so we are unable to control the animations.
Have you ever had this issue ?
Any insight on this ?

Retrieving entries from a SCNSceneSource
only works for Collada files. When working with USDZ file you'll have to traverse the node hierarchy and retrieve the animation from the node that holds it using -animationPlayerForKey:
.
nice, could you explain why ?
