Unreal AR Archviz Navigation

I need an Unreal Engine specialist who can turn an architectural model into an AR-ready experience that lets users walk the space through on-device navigation cues rather than simple object placement. The core of the job is to set up reliable, smooth navigation in augmented reality so a client can explore the design at true scale on site or in an open area.

Here’s what I will hand over:
• The optimized Unreal Engine project containing the full Archviz scene (materials, lighting, and baked assets).
• Reference videos that illustrate the kind of waypoint‐to-waypoint movement I’m after.

Your side of the work:
• Configure AR session (ARKit / ARCore) inside Unreal so tracking is tight and drift is minimal.
• Build an intuitive navigation system (tap-to-move, waypoint icons, or similar—open to your proven approach) that keeps users oriented in real space.
• Package and deliver an .ipa/.apk that I can test on both iOS and Android.

Acceptance will be based on:
• Accurate real-world scale alignment.
• Stable tracking for at least five minutes of continuous movement.
• Smooth waypoint transitions with no visible frame hitches on recent devices.

Please send links or builds that show comparable navigation work you have already shipped; past work is the main criterion I’ll use to choose a freelancer. The timeline is four weeks from kickoff, so only reach out if you can commit and hit that window.
