Reply to ParticleEmitterComponent Position Offset Issue After iOS 26.1 Update – Seeking Solutions & Workarounds
On iPhone 17 Pro with iOS 26.3.1, ParticleEmitterComponent impact VFX appear visually rooted near the device / the world pose from when tracking stabilized, not at the intended world-space hit, even though the host entity hierarchy is correct: we parent clones under ground_anchor with convert(position:from: nil) from world hits, and runtime logs show holderOriginWorld matches requestedWorldPos with worldPosErrM = 0, so this is not an app-side anchor math bug. particlesInheritTransform = true (Apple’s suggested workaround) does not fix the visible misplacement. This matches the ParticleEmitterComponent / transform regression discussed around iOS 26.1+ (e.g. forum thread / FB21346746). We’re looking for confirmation, workarounds, or a fix timeline from Apple Engineering.

I am experiencing same issue on my end, has anyone found a solution for this? Device: iPhone 17 Pro OS: 26.3.1 Symptom: particles appear tied to device pose at world-anchor stabilization, not at subsequent AnchorEntity(world:) hit spawns
