How to patch game using RuntimePatcherFramework in UE5
RuntimePatcherFramework:
is a runtime patching + DLC delivery framework for Unreal Engine projects. It targets live-service, MMO, and PC games that need to ship new content without a full store update, by downloading patch payloads from HTTP, validating integrity, and mounting `.pak` containers at runtime.
Fetch patch indexes and manifests over HTTP
-Supports `latest.json` (main version + folders) and `content_groups.json` (group id → folder mapping).
-Downloads and parses manifests into a unified `FPatchFileInfo` list for the downloader/validator.
Download patch payloads (chunks / pak-like files) at runtime
-The Framework can handle file larger than 50GB!
-The framework uses Direct-to-Disk Streaming, meaning it writes data directly to storage without filling up the RAM. This ensures rock-solid stability regardless of the patch size.
-Queue-based downloader with global progress reporting (bytes/percent/speed + current file).
-Incremental or full queue modes, plus scanned-entry modes for multi-directory installs.
-Safe URL handling (encodes path segments) and retry handling.
Validate downloaded content
-Quick launch scan (fast “is update available?” check).
-Fast verify (size + optional hash) and full integrity verification (MD5 vs manifest hash).
Cancel support for long scans and verify operations.
Optional “delete corrupted chunks immediately”.
Mount downloaded containers
-Mounts `.pak` recursively from one or multiple directories.
-Blueprint delegates for mount progress and completion.
Blueprint-friendly workflow
-Core systems are exposed as GameInstance subsystems (easy to access in Blueprints).
-Includes a Blueprint function library with helpers for paths, hashing, IO, URL building, and settings access.
