Foundry 0.17.2 preview — the editor, Room and Sandbox for macOS and Windows

An unsigned preview. 0.17.2 adds Foundry Editor, the content editor, as a download for macOS and Windows. Room and Sandbox are the same 0.17.1 files as before.

New to Foundry? It is an engine library, not an installer: a game is its own repository that depends on it. Getting started goes from an empty folder to a window. It is not a signed or notarized release; certification waits until after a fully playable 3D game exists on Foundry (ADR-0047).

Opening them

Because these builds are unsigned, your system warns the first time.

macOS (macOS 26 or later, Apple Silicon):

1. Unzip, and move the app anywhere you like.
2. Open it. macOS says it cannot verify the app. Choose Done.
3. Go to System Settings → Privacy & Security, scroll down, and choose Open Anyway beside the app's name. Confirm.

After that it opens normally.

The editor is a folder rather than an app: double-click bin/foundry-editor, which opens in Terminal, and use Open Anyway the same way. With no arguments it creates workspace/ beside itself to work in; --help lists the options.

Windows (Windows 10 or 11, x64, with a GPU driver supporting Vulkan 1.3):

1. Unzip the whole folder anywhere; nothing is installed.
2. Run bin\room.exe, bin\sandbox.exe or bin\foundry-editor.exe.
3. When "Windows protected your PC" appears, choose More info → Run anyway.

Checking your download

Compare against SHA256SUMS.txt:

• macOS: shasum -a 256 Foundry-Room-macos-arm64.zip
• Windows: Get-FileHash Foundry-Room-windows-x64.zip

A matching checksum shows the file is the one published here. It is not a signature.

Known limits

• Windows is tested on one GPU, an Intel Arc A750.
• macOS was checked in a macOS virtual machine, not on a separate physical Mac.
• Linux is not included. Foundry's servers run on Linux, but no Linux window or graphics driver has been tested yet.
• The sandbox's multiplayer mode needs operator certificates; see the networking guide. Both samples run offline by default.

Room and Sandbox are built from c37c01d; the editor from b9a8973. The Windows editor was cross-compiled on macOS, staged by the same release tool, and run on the Windows test PC. Each zip holds an inventory.txt listing every file's size and SHA-256, and a THIRD_PARTY_NOTICES.txt.

Foundry 0.17.1 preview — Room and Sandbox for macOS and Windows

Superseded by v0.17.2-preview, which adds the editor.

An unsigned preview. 0.17.1 replaces 0.17.0: on Windows the program no longer opens a console window beside the game. This is Foundry's first public download: its two sample applications, for macOS and Windows. It is not a signed or notarized release; certification waits until after a fully playable 3D game exists on Foundry (ADR-0047).
