The best way to use passthrough on visionOS 2.x is NOT to invoke the Control Center, but to look away from the scene and invoke "Force Quit" (simultaneously press and hold the top button and Digital Crown). Unlike the Control Center method, invoking "Force Quit" with passthrough on activates the passthrough feed WITHOUT dimming it, which is awesome.
Unfortunately, the first beta of visionOS 26 breaks this. "Force Quit" doesn't activate the passthrough feed at all. And even the Control Center method is glitchy, activating the passthrough feed only with a directional gaze (meaning depending on the position, it may be hard to have both the Control Center panel out of the way AND the passthrough feed working).
Anyway, I share @Jjhooke69 's question. @doublevr , can you please comment, especially since visionOS 26 is no longer a mystery, on what kind of passthrough (if any) will be possible in the Hyper app and when this'll all hit? I'm not sure whether it would be possible to implement an on-device AI solution that would allow passthrough without the camera feed ever leaving the device, since it looks like Apple is being "principled." By the way, great work on SLR in general. It's always been and remains the cutting edge platform for this kind of fun. Thanks.
