Transform order issues in the Reality Composer Pro inspector

FB16078162

When tweaking values in RCP's transform inspector, particularly those associated with rotation in world space, the behavior is unreliable. Some extra logic seems to be happening to avoid incorrect transforms; however, the results do not always appear correct. For example, in the attached video, while adjusting X and Y, the inspector automatically populates the Z rotation, making even restoring the original transform difficult. https://youtu.be/rA2Sp9xd4Ko

Async loading equipment

FB16078151

The requirements for game equipment loading during setup, which we were unable to find any prior references for, took us off guard as I tried to control the loading flow. Using await "Entity(named" instead of the synchronous version leads to a silent failure that doesn't display the equipment ultimately. We found a reference on the forums involving using placeholder entities and recalculating the bounding box, but I'm not sure if this is the correct technique to asynchronously load entity equipment and feed it back into the system.

if let focusGreenEntity = try? await Entity(named: BundleAssets.focusGreenEntity, in: realityKitContentBundle) {
  if let equipment = game?.setup.colorEquipment.first(where: { $0.id == .FocusBlend.greenID }) {
    equipment.entity.addChild(focusGreenEntity)
    let bbox = focusGreenEntity.visualBounds(relativeTo: equipment.entity)
 game?.tabletopGame.addAction(.updateEquipment(equipment, boundingBox: Rect3D(bbox)))

AccessibilityComponent custom rotors breaks VoiceOver

FB13769967

When you try to listen to a custom rotor navigation event inside an AccessibilityComponent, the RealityRender stops working as it would normally. It looks like the .customRotors collection property is emptied, but there are no signs of Entity reconstruction. The focus is also lost, and other entities with custom rotors are reset too. After running the custom rotor on the video, it was impossible to get back to focus, and VoiceOver acted anxious.
