Interesting! I'm totally new to RealityKit (long time Unity dev) and was wondering if it was something like this. But it seems the docs insist "RealityKit calls every system’s update(context:) method every frame". Probably the docs need updating with visionOS, eh?

@arthurfromberlin I tried that just now and IT WORKS! 🥳 But... can you explain in more depth WHY that works? I'm familiar with scheduling of systems from Bevy, so I understand that systems might be ticked at different times, but the query happens INSIDE the system, after my console log no less. I really don't understand why that would dictate when the system's update function is called. Thank you so much for the tip!
