Every Windows job and Linux x86 were failing; reproduced each locally (MSVC 18 x64/x86, gcc -m32) and fixed: - studio.cpp: thumbnail buffers were named `small`, which Windows' rpcndr.h #defines to `char`, so MSVC saw `std::vector<u8> char(...)`. Renamed to `scaled`. (All three Windows builds.) - 32-bit x86: astcenc's SSE4.1 code calls __builtin_popcountll on 32-bit MSVC, which doesn't exist; 32-bit builds now use astcenc's plain backend. - opus defaulted to the DLL C runtime while the app links the static one; x86 MSVC can't link that mix (__except_handler4_common). OPUS_STATIC_RUNTIME. - 32-bit gcc/clang: turn on SSE2 (-msse2 -mfpmath=sse) as MSVC does; rtm (under ACL) uses SSE intrinsics on any x86. - CI Linux x86: install the i386 X11 dev packages; GLFW couldn't find a 32-bit libX11 to link. The x86 and x64 Windows builds pass the same --selftest checks (97/104; the 7 failures are pre-existing and identical on both). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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
- Download Frame Studio for your computer from the Releases page (Latest build, or a version release) and unpack it. See Getting started.
- Prepare the headset once: developer mode, SSH and a key. See Preparing the Steam Frame.
- Install Frame Home: in Studio, Headset > Install on Steam Frame..., then Install Frame Home. See Installing Frame Home.
- Open a home: File > Open... and pick a Meta home
.apk, a.fenvor a model. - Send it: Headset > Send to Frame. Put the headset on: you are standing in it.
Downloads
Every push builds everything. The newest build of main is always on the Releases page as Latest build; tagged
versions (v1.0, ...) get their own release. Builds of other branches are under Actions (open a run, then
Artifacts).

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.
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),
.fenvenvironments 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
.fenvfiles and leaves out what can't be seen; sends them to the headset in one click. - Packs several environments into one
.fbundleto 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 |
The headset side is built on the Steam Frame; a ready-built copy is in frame/payload/. Full details, prerequisites
and the CI: docs/building.md.
