Frame Studio and Frame Home

Frame Home makes your homes the Steam Frame's environment. Meta Quest homes (HSL, Clay .opa, glTF) and models become Frame-native .fenv environments, drawn in SteamVR's compositor in place of its own environment: at boot, behind the Steam menu and while games load. Frame Studio is the desktop editor for them, on Windows, Linux and macOS. It opens Meta homes, .fenv environments and models (glTF, FBX, OBJ), shows them with the same renderer the headset runs, and lets you edit, save and send them to the headset.

Quick start

1. Download Frame Studio for your computer from the Releases page (Latest build, or a version release) and unpack it. See Getting started.
2. Prepare the headset once: developer mode, SSH and a key. See Preparing the Steam Frame.
3. Install Frame Home: in Studio, Headset > Install on Steam Frame..., then Install Frame Home. See Installing Frame Home.
4. Open a home: File > Open... and pick a Meta home .apk, a .fenv or a model.
5. Send it: Headset > Send to Frame. Put the headset on: you are standing in it.

Downloads

Every push builds Frame Studio and its matching Frame Home payload. The Latest build release contains both Studio packages and FrameHome-installer.zip; each v* version release contains both products too. Studio updates from its top bar, and Frame Home updates from the Environments panel on the headset. Both use the same release channel.

Computer	Frame Studio
Windows, 64-bit PCs	FrameStudio-windows-x64.zip
Windows, 32-bit	FrameStudio-windows-x86.zip
Windows on ARM (Snapdragon, Surface Pro X...)	FrameStudio-windows-arm64.zip
Linux, 64-bit PCs	FrameStudio-linux-x64.tar.gz
Linux, 32-bit	FrameStudio-linux-x86.tar.gz
Linux on ARM (Raspberry Pi 5, ARM laptops, the Steam Frame's desktop)	FrameStudio-linux-arm64.tar.gz
Mac with Apple Silicon (M1 and later)	FrameStudio-macos-arm64.zip
Mac with Intel	FrameStudio-macos-x64.zip
Frame Home only, installed from any computer	FrameHome-installer.zip

Studio needs a GPU with Vulkan 1.2: any recent NVIDIA, AMD or Intel driver on Windows and Linux. On a Mac, Vulkan runs on Metal through MoltenVK, which comes inside the app. The 32-bit builds have at most 4 GB to work in, so the very largest homes may not fit.

See Installing Frame Home for how to install the runtime on a Steam Frame.

Highlights

Frame Home (on the headset)

• Takes SteamVR's environment slot natively: no app, no library entry, controllers and passthrough still work.
• An Environments panel in the Steam menu: switch homes live, delete them, change settings, debug views.
• Walk, teleport, snap or smooth turn, sit in seats, gravity zones, comfort vignette.
• Built for 120 fps: baked environments, eye-tracked foveation, auto resolution, per-world tuned settings, and a thermal governor that keeps the headset cool.
• Safe: a compositor layer that steps aside if Frame Home stops, and a one-file off switch.

Frame Studio (on your computer)

• Opens Meta homes (HSL, Clay, glTF), .fenv environments and Blender or Unity models; pairs rooms with vistas.
• Move, rotate, scale, hide and delete objects, with undo and auto-saved versions.
• Shape the walkable area: auto-generated surfaces, drawn floors, spawns, seats, hotspots, gravity zones.
• Add a background sound and a picture; set and calculate per-world settings.
• Saves baked .fenv files and leaves out what can't be seen; sends them to the headset in one click.
• Packs several environments into one .fbundle to share or install together (bundles).
• Debug views (wireframe, meshes, GPU cost, overdraw), a home report, and the headset's settings and debug page from your desk.
• A navigation gizmo in the viewport corner: drag it to orbit, click an axis to snap to that view.
• Themes, from dark to light, drawn from the MetaDB palette (Window > Theme).

Building from source

Everything Studio needs is in third_party/; you need CMake 3.16+ and Ninja. In short:

On	Command
Windows (Visual Studio 2022 with C++)	studio\build_windows.bat x64 (or x86, arm64)
Linux, macOS	scripts/build-studio.sh <target>... or scripts/build-studio.sh all

Frame Home binaries are built in GitHub Actions and are not checked into frame/payload/. Full details, prerequisites and CI: docs/building.md.
