Export Pipeline in Godot 4.3+

All examples target Godot 4.3+ with no deprecated APIs. GDScript is shown first, C# follows where applicable.

1. Export Presets

Creating Presets in the Editor

Open Project → Export, click Add…, and select the target platform. Each preset maps to one entry in export_presets.cfg. You can create multiple presets for the same platform (e.g., a debug build and a release build for Windows).

Required one-time setup per platform:

• Export Templates must be downloaded via Editor → Export Templates.
• Platform-specific toolchains (Android SDK, Xcode, etc.) must be installed separately.

export_presets.cfg

Godot writes export_presets.cfg to the project root. Commit this file — it is safe and contains no secrets. Secrets (codesigning passwords, keystore passwords) must never be committed; use environment variables instead.

Example preset structure (Windows release):

[preset.0]
 
name

Godot regenerates export_presets.cfg on every editor save. Do not hand-edit it while the editor is open.

⚠️ Changed in Godot 4.7: The "runnable" flag moved out of export presets — runnable= (shown in the example above for 4.3–4.6) is no longer a per-preset property in export_presets.cfg; the editor now tracks which preset is runnable separately. Don't be surprised when the line disappears from the file after saving in a 4.7 editor. See GH-114930.

Godot 4.7+: Sparse PCK exports (patch packs) support encrypting the file index, complementing the existing encrypt_pck / encrypt_directory preset options. (GH-113920)

2. Platform-Specific Settings

3. Export from CLI

Run Godot in headless mode to export without opening the GUI. This is the standard approach for CI/CD.

Release Export

Debug Export

Export .pck Only (no executable)

Use --export-pack when you only want to ship updated game data alongside a fixed engine binary (e.g., DLC or patch distribution):

Godot 4.7+: When exporting patch PCKs for Android, an APK or AAB can be provided as the base pack, extending PCK-patching workflows to Android builds. (GH-116553)

Packing In-Memory Data (Godot 4.7+)

PCKPacker.add_file_from_buffer(target_path, data, encrypt = false) packs a PackedByteArray straight into a PCK — no temp file on disk — which is handy when generating patch content from a build script:

Key CLI flags

The preset name in the CLI flag must match name= in export_presets.cfg exactly, including capitalisation and spaces.

4. CI/CD with GitHub Actions

Run godot --headless --export-release inside a GitHub Actions matrix that builds Windows, Linux, and Web artifacts on every push and tagged release. Use chickensoft-games/setup-godot@v2 to install the engine + export templates (set use-dotnet: true for C# projects). Inject the version from git describe before export so application/config/version is correct in the binary.

See references/ci-cd-github-actions.md for the full .github/workflows/export.yml with matrix presets, artifact upload, and Linux executable bit handling.

5. Versioning

Set the version in application/config/version and read it at runtime with ProjectSettings.get_setting(). To inject a version from git at export time, run an EditorScript that calls git describe --tags --always --dirty through OS.execute() before the export step. Tags follow Semantic Versioning (v1.2.3).

See references/versioning.md for the runtime version label, the inject_version.gd tool, and the tag convention.

6. Distribution: itch.io and Steam

itch.io uses the Butler CLI: butler push build/windows/ my-studio/my-game:windows --userversion "$VERSION". Channel names follow a convention (windows, linux, macos, web, android). In CI, the Ayowel/butler-to-itch@v1 action pushes all artifacts at once; store the API key as the BUTLER_API_KEY secret.

Steam requires three pieces: the Steamworks SDK (non-redistributable, keep out of public repos), the GodotSteam addon for engine bindings, and depot configurations driven by steamcmd +run_app_build app_build.vdf. Steam integration is outside the export pipeline itself.

See references/distribution-itch-steam.md for full butler install instructions, channel naming table, the deploy-itch GitHub Actions job, and the Steam component breakdown.

7. Shader Baker (Godot 4.5+)

Godot 4.5 introduces the Shader Baker, an export-time tool that pre-compiles shaders for the target platform. Without it, shaders compile at runtime on first use, causing visible hitches when new materials are first rendered in-game. The Shader Baker eliminates this stutter by doing the work at export time.

Enabling

In Project → Export, open a preset and locate the Shader Baker section. Enable it and configure target backends (Vulkan, D3D12, Metal, GLES3) as needed.

The Shader Baker increases export build time but has no effect on game download size or runtime memory. The pre-compiled cache is embedded in the .pck file.

Impact by Platform

CI Workflow Note

The Shader Baker runs automatically when exporting via the editor GUI or CLI (--export-release). No extra steps are needed in CI — it is controlled by the preset configuration, not a separate CLI flag.

8. Windows Export — Native Resource Editing (Godot 4.5+)

Before Godot 4.5, modifying .exe metadata (version info, icon, copyright, company name) on Windows required the external rcedit tool. Godot 4.5 handles all of this natively at export time — no rcedit download or configuration needed.

What is Edited Natively

Setup

1. Open Project → Export → Windows Desktop preset.
2. Fill in the application/* fields under Application in the preset options.
3. Export normally — Godot writes the metadata into the .exe directly.

Removing rcedit from CI: If your project previously downloaded rcedit in CI and called it as a post-export step, you can remove that step. The fields in the export preset replace it entirely for Godot 4.5+.

9. Checklist

• Export templates downloaded for the target Godot version (Editor → Export Templates)
• export_presets.cfg committed to version control
• Secrets (keystore passwords, codesign passwords, API keys) stored in env vars or CI secrets, never in the file
• Each preset has a unique name= that matches the CLI --export-release argument exactly
• Output directories created before the export command runs (mkdir -p)
• Linux binary marked executable after export (chmod +x)
• application/config/version in project.godot is populated at export time from a git tag
• Web export: hosting server sends COOP + COEP headers if threads are enabled
• Android release preset uses a signed keystore, not the debug keystore
• macOS builds intended for distribution are codesigned and notarized
• Artifacts are uploaded per-platform in CI so individual platform builds can be downloaded
• itch.io channels follow the naming convention (windows, linux, macos, web, android)
• Butler API key stored as a CI secret, not hardcoded
• Steam depot configs are kept out of public repositories
• Shader Baker enabled in export presets for macOS, D3D12, and mobile targets (Godot 4.5+)
• Windows .exe metadata (version, icon, company name) set in the export preset — rcedit no longer required (Godot 4.5+)
