How to view 3D models on Pico 4 and Pico 4 Ultra

Open 0xr.space in the Pico browser, press Open and choose a file, then press View in your space. There is nothing to install: the page uses WebXR, which the headset browser has. Where the browser offers an immersive-AR session the model is placed in your room over passthrough; where it offers only immersive VR, the page opens that instead, at the same size.

The page recognises the Pico browser by name and treats it as a headset: a heavy model is shown as a lighter copy of about 690,000 triangles, as on a Quest 3. Two limits. A web page cannot reach a Pico's cameras, so Scan cannot read a QR code there, and the free Model Explorer app is on the Meta Horizon Store only. As of 20 October 2026 the viewer has not been tried on a Pico.

Steps

  1. Put the file where the headset can reach it: a cloud drive opened in the Pico browser, or a USB cable into the headset's storage.
  2. Open 0xr.space in the Pico browser and press Open.
  3. Choose the file. A heavy model is copied into a lighter one the first time, once.
  4. Press View in your space, allow what the browser asks, and use the controllers to place and turn the model.

Questions

Is there a Model Explorer app for Pico?

No. The app is on the Meta Horizon Store for Quest 3 and Quest 3S. On a Pico, the website does the same work in the browser.

Will the model be in my room or in VR?

That depends on the browser. If it offers immersive-AR, the model stands in your room; if it offers only immersive VR, it stands in a virtual space. Either way it opens fitted to about 70 cm; press Scale, then 1:1 Size, for the size the file gives it.

Can I open a link from my computer with Scan?

No. The page cannot use the Pico's cameras. Type the link into the Pico browser instead, or copy the file over by cloud drive or USB.

How do I sign in on a Pico?

With a 6-digit code sent to your email. Sign in with your phone needs a headset camera, so it is not offered there.

Is my file uploaded?

No. It is read and copied on the headset, and nothing is sent to a server unless you create a share link yourself.
