- ImGuizmo is compiled with -fno-strict-aliasing on GCC/Clang: its type punning let Clang for x64 turn gizmo drags into NaN transforms - 32-bit: the .fenv packer keeps LZMA within a 32-bit address space (saves failed with out-of-memory); failed saves are logged - std::to_string of file times and the 32-bit descriptor handle cast compile on every standard library - Linux fonts: Noto Sans, then Liberation Sans, then DejaVu; the Play/Pause button sizes to its label; macOS fonts are rasterized at Retina density - self-test stages allow at least 3000 frames (software GPUs draw ~30 a second) - headset payload rebuilt from this source 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,
converted into Frame-native .fenv environments and drawn in SteamVR's compositor in place of its own.
Frame Studio is the desktop editor for them. It opens Meta homes, .fenv environments and models (glTF, FBX,
OBJ), shows them with the same renderer the headset runs, and lets you move, hide and delete objects, shape the walkable
area, add sounds and pictures, save environments and install them on the headset.

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: the very largest homes may not fit.
Frame Home without Studio: FrameHome-installer.zip installs it on the headset from any computer (or on the
headset itself); see frame/README-frame-home.txt inside it.
Building
Everything Studio needs is in third_party/ (Vulkan is loaded at runtime). CMake 3.16+ and Ninja.

Linux builds need the X11 headers (libx11-dev libxrandr-dev libxinerama-dev libxcursor-dev libxi-dev) and, for
linux-x86, gcc-multilib g++-multilib. Packages land in dist/.
The headset side (frame-home, frame-switcher, fenv-tool, the compositor layer) is built on the Steam Frame
itself against SteamVR's own OpenVR library: the top-level CMakeLists.txt, then
g++ -O2 -shared -fPIC -std=c++17 layer/frame_home_layer.cpp -o build/layer/libframe_home_layer.so. Its ready-built
copy is frame/payload/, which every Studio build and the installer carry.
