AnimatedSprite not run while implemented on a View3D Node?

MeganeSenpai

So I have an animated sprite implemented in a View3D node similar to this:

View3D {
    id: root
    environment: environment
    camera: camera01
    width: parent.width
    height: parent.height
    visible: true
    Node {
         id: imageNode
         visible: true
         position: Qt.vector3d(-2, 0, -70)
         scale: Qt.vector3d(0.01, 0.01, 0.01)

         Rectangle {
                id: testRect
                width: 250
                height: 250
                visible: true
                color: "transparent"
                border.color: "#ec001c"
                border.width: 3
                radius: 5

                SpriteSheetAnimation {
                     id: testSprite
                     visible: true
                     source: "path/to/image.png"
                     frameCount: spriteCount
                     frameWidth: spriteWidth
                     frameHeight: spriteHeight
                     frameRate: 30
                     loops: AnimatedSprite.Infinite

                     onCurrentFrameChanged: {
                         console.log("Sprite current frame = " + currentFrame)
                     }
                 }
            }
    }
}

And it only shows the first frame of the animated sprite, despite the logs shows that the currentFrame keeps increasing.

I tried moving the exact code of the SpriteSheetAnimation to a 2D view, and it runs just fine, so I don't think the sprite nor the asset is the problem here.

I'm using QT version 6.2.4

Please help me identify the issue here. Or if I shouldn't use Node, which should I use instead for the image to be updated? Thank you.

I suggest you try with the latest Qt version (6.9 atm) first and if that does not work, create a bug report at https://bugreports.qt.io/

@Jonas-Karlsson Unfortunately I'm working on a sizable project for a company so I can't upgrade QT version if I want to.
Also, I'm not sure if it was a bug or that's how nodes are intended to work and I'm just uninformed, as I'm quite new to QT. That's why I'm asking if there is any alternate method to implement it.
Thank you,

Hi and welcome to devnet,

While I understand the lock you are into, testing with a more recent version can help you check whether what you actually have is working. Two possible outcomes:

it does and you can try to back port the changes needed
it does not and you have to check if it's an issue (and possibly fill a new ticket about it)
