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="Windows Desktop"
platform="Windows Desktop"
runnable=true
dedicated_server=false
custom_features=""
export_filter="all_resources"
include_filter=""
exclude_filter=""
export_path="build/windows/MyGame.exe"
encryption_include_filters=""
encryption_exclude_filters=""
encrypt_pck=false
encrypt_directory=false

[preset.0.options]

custom_template/debug=""
custom_template/release=""
debug/export_console_wrapper=1
binary_format/embed_pck=true
texture_format/s3tc_bptc=true
texture_format/etc2_astc=false
binary_format/architecture="x86_64"
codesign/enable=false
codesign/identity=""
codesign/password=""
codesign/timestamp=true
codesign/timestamp_server_url=""
codesign/digest_algorithm=1
codesign/description=""
codesign/custom_options=PackedStringArray()
application/icon=""
application/console_wrapper_icon=""
application/icon_interpolation=4
application/file_version=""
application/product_version=""
application/company_name=""
application/product_name=""
application/file_description=""
application/copyright=""
application/trademarks=""
application/export_angle=0
application/export_d3d12=0
application/d3d12_agility_sdk_multiarch=true
ssh_remote_deploy/enabled=false
ssh_remote_deploy/host="user@host_ip"
ssh_remote_deploy/port="22"
ssh_remote_deploy/extra_args_ssh=""
ssh_remote_deploy/extra_args_scp=""
ssh_remote_deploy/run_script="#!/usr/bin/env bash\nexport DISPLAY=:0\n\"{temp_dir}/{exe_name}\" {cmd_args}"
ssh_remote_deploy/cleanup_script="#!/usr/bin/env bash\nkill $(pgrep -x -f \"{temp_dir}/{exe_name} {cmd_args}\")\nrm -rf \"{temp_dir}\""

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

Platform	Key Setting / Consideration
Windows	Set application/icon (.ico file). Codesigning requires a .pfx certificate; set codesign/enable=true and supply codesign/identity + codesign/password via env vars. Without codesigning, Windows SmartScreen will warn users.
Linux	No codesigning required. After export, run chmod +x MyGame.x86_64 on the binary. Ship as a tarball or AppImage for distribution.
macOS	Requires notarization for Gatekeeper to allow launch without warning. Set codesign/enable=true and notarization/enable=true. Provide the codesign/identity (Apple Developer ID). The Info.plist entries (bundle ID, version, display name, privacy usage descriptions) are set under application/* options in the preset. Notarization is done post-export via xcrun notarytool.
Web	Requires SharedArrayBuffer for multi-threading — the web server must send Cross-Origin-Opener-Policy: same-origin and Cross-Origin-Embedder-Policy: require-corp headers. Disable threads (rendering/threads/thread_model=0) if hosting on a server you cannot configure. Exported output is a .html + .js + .wasm + .pck bundle.
Android	Requires a keystore for release signing. Set keystore/release to the .keystore path and supply keystore/release_user + keystore/release_password via env vars. Declare permissions in the preset under permissions/*. Set package/unique_name to a reverse-DNS string (e.g., com.studio.mygame).
iOS	Requires a valid Apple provisioning profile (.mobileprovision). Set application/bundle_identifier, codesign/identity, and application/provisioning_profile. Distribution builds require an App Store distribution certificate.

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

godot --headless --export-release "Windows Desktop" build/windows/MyGame.exe

Debug Export

godot --headless --export-debug "Windows Desktop" build/windows/MyGame.exe

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 --headless --export-pack "Windows Desktop" build/windows/MyGame.pck

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:

var build_info: String = "v" + ProjectSettings.get_setting("application/config/version", "dev")
var packer := PCKPacker.new()
packer.pck_start("user://patch_1.pck")
packer.add_file_from_buffer("res://data/build_info.txt", build_info.to_utf8_buffer())
packer.flush()

string buildInfo = "v" + ProjectSettings.GetSetting("application/config/version", "dev").AsString();
var packer = new PckPacker();
packer.PckStart("user://patch_1.pck");
packer.AddFileFromBuffer("res://data/build_info.txt", buildInfo.ToUtf8Buffer());
packer.Flush();

Key CLI flags

Flag	Purpose
--headless	No display server; required for server/CI environments
--export-release "Preset Name" path	Export using release template
--export-debug "Preset Name" path	Export using debug template
--export-pack "Preset Name" path	Export .pck resource pack only
--quit-after N	Quit after N milliseconds (rarely needed for export)

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

Reading the Version at Runtime

Store the version string in Project → Project Settings → Application → Config → Version. Then read it anywhere:

# version_label.gd
extends Label

func _ready() -> void:
    text = "v" + ProjectSettings.get_setting("application/config/version", "dev")

// VersionLabel.cs
using Godot;

public partial class VersionLabel : Label
{
    public override void _Ready()
    {
        Text = "v" + ProjectSettings.GetSetting("application/config/version", "dev").AsString();
    }
}

Auto-Versioning from Git Tags

Tag your release commit, then inject the version at export time. The CI workflow above does this via sed, but you can also run a pre-export GDScript tool (EditorScript) if you prefer to keep it in-engine:

# tools/inject_version.gd  — run with: godot --headless --script tools/inject_version.gd
@tool
extends EditorScript

func _run() -> void:
    var git_output: Array = []
    var exit_code := OS.execute("git", ["describe", "--tags", "--always", "--dirty"], git_output)
    if exit_code != 0:
        push_error("inject_version: git describe failed")
        return

    var version: String = (git_output[0] as String).strip_edges()
    ProjectSettings.set_setting("application/config/version", version)
    var err := ProjectSettings.save()
    if err != OK:
        push_error("inject_version: failed to save project.godot — error %d" % err)
    else:
        print("inject_version: set version to '%s'" % version)

Run it as part of a CI step before the export step:

godot --headless --script tools/inject_version.gd
godot --headless --export-release "Windows Desktop" build/windows/MyGame.exe

Version Tag Convention

Use Semantic Versioning tags: v1.2.3. git describe then produces v1.2.3-4-gabcdef for commits after a tag, giving you fully traceable builds.

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

Platform	Backend	Benefit
macOS / Apple Silicon	Metal	Up to 20x load time reduction on complex shader graphs
Windows	D3D12	Eliminates D3D12 pipeline state compilation stalls
Mobile (Android/iOS)	GLES3	Faster first-render on mid-range hardware
Linux / Windows	Vulkan	Moderate improvement; Vulkan caches vary by driver

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.

# Shader Baker runs as part of normal export (no extra flag needed).
godot --headless --export-release "Windows Desktop" build/windows/MyGame.exe

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

Export Preset Field	Effect on .exe
application/file_version	File version shown in Properties → Details
application/product_version	Product version
application/company_name	Company name
application/product_name	Product name
application/file_description	Description
application/copyright	Legal copyright
application/icon	.ico file embedded as the executable icon

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+)
