🧾 Release Notes: 1.5

🧩 Latest Update — Version 1.5

Update 1.5 focuses on tighter multiplayer audio synchronization, flexible music source selection, and improved controller navigation.

• Improved replicated playback timing by using Game State’s shared server world time, reducing audio drift between the listen server and connected clients

• Reworked the previous Radio/Disc toggle into a flexible source-cycling system that only includes the playback modes supported by each Music Player

• Improved controller navigation and conditional button behavior throughout the Music Controls UI

• Previous Disc and Next Disc controls are now automatically hidden for single-disc Music Players

• Added additional Music Player reference validation to server requests

• Removed unused functions, nodes, and outdated source-specific logic

These improvements provide more consistent multiplayer playback, cleaner UI navigation, and a more extensible foundation for supporting additional music sources in future updates.

Overview

Bring your world to life with the BR MusicSystem, the definitive Blueprint framework for in-game interactive audio. From cozy social hubs and farming sims to survival games and sprawling RPGs, this system adds depth and atmosphere with synchronized music that just works in multiplayer.

• Server-Authoritative and Optimized – State changes replicate through RepNotify, while shared server-world timing keeps playback tightly synchronized without continuously replicating playback position

• Flexible Music Sources – Configure each Music Player to support Radio, Disc, or both. Source controls and disc navigation automatically adapt to the capabilities of each device

• Dynamic Radio Stations – Create unlimited, globally synchronized stations with weighted playlists and configurable Audio Inserts such as DJ drops, advertisements, and jingles

• Collectible Disc System – Build persistent player collections with save/load support, disc pickups, and configurable tray capacities ranging from single-disc players to multi-disc changers

• Vehicle Stereo Support – Add a drop-in vehicle stereo with configurable interaction and interior listening bounds for driver-only, passenger, or full-cabin control

• Access and Lockout Logic – Manage multiplayer access with optional locks, idle timeouts, and fair-use rules designed to reduce player griefing

• Simple Core Setup – A focused set of managers, actors, and components handles radio playback, disc playback, player interaction, vehicle audio, and saving

• Customizable Event-Driven UI – Includes two-line dynamic displays, marquee scrolling, adaptable UMG controls, and fire-and-forget notifications without relying on Event Tick for gameplay logic

• Blueprint-Only and Extensible – Cleanly organized and commented Blueprints designed for extension with custom content, new stations, additional device types, and future playback sources

• Cross-Platform Ready – Fully Blueprint-based and tested on Windows and Mac for straightforward use across Unreal-supported platforms
