Before you install

Notes and requirements.

Graphics

A GPU with Vulkan, Direct3D 12 or Metal. Lumit is GPU-first; there is no software-rendering fallback.

Windows

Run the installer. It registers .lum and .lumfx so projects open on double-click. SmartScreen will warn on first run — the build is not code-signed yet.

Linux

Unpack and run ./lumit_flutter. FFmpeg ships inside the bundle. For a menu entry and file associations, see INSTALL.txt in the archive.

macOS

Apple silicon only, and not notarised — Gatekeeper will refuse it on first open. Right-click the app and choose Open to get the override prompt. The macOS pass is still in progress, so treat this build as experimental.

Building it yourself

Clone the repository and follow the README. The engine is Rust, the interface is Flutter; CI builds these same artefacts on every tagged release.
