Install the free Model Explorer app from the Meta Horizon Store. Then, on a 3D file in the headset's Files app, a chat, a mail or the browser's downloads, choose Open with, or Share, and pick Model Explorer. The app copies the file, opens its immersive session and loads the model there, the way a file picked inside the app is loaded. Nothing is uploaded.
It takes every format Open does, from GLB, USDZ, STL and OBJ to STEP, SketchUp, splats and ZIP, RAR or 7z archives, up to 2 GB at a time, and several files in one Share. Many apps label a .glb as a generic binary file, so the chooser may list other apps beside Model Explorer. It needs the app version released on 19 October 2026 or later; in the Quest browser, press Open instead.
The app was not given the file's contents. Save the file to the Download folder, open Model Explorer and pick it there.
Yes. Select the .obj, the .mtl and the images together and Share them in one go, or share a ZIP of the folder.
No. It is copied into the app's own storage on the headset, handed to the viewer, and the copy is deleted once sent. Nothing goes to a server unless you create a share link yourself.
The Store app lists only Quest 3 and Quest 3S. On a Quest 2, open the file with Open in the Quest browser at 0xr.space.
