How the system works

The radio system is driven by a single Data Asset that contains all audio content. This asset is exposed in the Details panel and can be swapped out easily if needed.

Inside the Data Asset, you store everything you want the radio to play. Adding, removing, or modifying content is as simple as editing this asset.

When the radio is turned on, it loads every entry from the Data Asset and begins playing the content for the currently selected radio channel—either sequentially or in random order, depending on the user settings.

After a complete broadcast show has finished (i.e., all of its audio parts have played), the system automatically finds the next show on the same channel and plays it. If no unplayed shows remain, the playlist is cleared and, if enabled in the Details panel, the system restarts from the beginning.

If weather reports or advertisements are enabled, the system inserts them at random intervals between show segments. The maximum interval can be configured in the Details panel.

When the player switches channels at runtime, the system saves the current playback position, clears the current queue, and loads the new channel’s content. The previous channel continues playing in the backend of the system, so switching back feels like a realistic radio experience when flipping between stations.

All audio is routed through a MetaSound, where it is dynamically processed using the user’s radio effect settings.

The entire system runs from one master Blueprint and one master MetaSound asset, providing a centralized, easy-to-manage architecture.

Easy Setup

1. Data‐Driven Content
   All your audio assets live in a single, easy-to-swap Data Asset. Drag in your music tracks, show segments, ads, and weather clips—no blueprint tinkering needed.

2. Set Radio settings
   Drag and drop one of the desired decade radio blueprints into your scene and then customize the radio to fit your project. The radio settings come with a lot of pre-settings for each decade for a fast and easy setup.

3. That's it!
   On Begin Play the radio system will read the data asset information. And when powered on, the radio queues up content for the selected channel. Once one show ends, the system automatically finds the next fitting segment. When it runs out, it resets and starts fresh if reset is enable

Key Features

• Full-Era Broadcasts
  Pre-configured shows and music libraries spanning the 1900s through the 2020s—select a decade and you’re set.

• Procedural Composition at runtime
  Content is assembled on the fly: drop your clips into the Data Asset and let the system handle the rest, either randomly or in order.

• Specific First and Last Episode in a Broadcast show (Used In Random Mode)
  Attach a first or/and closing segment to any show for a polished episode start or finale.

• Power On/Off
  When you switch the radio off, it continues to play silently for 30 sec by default but can be changed in the details panel before the radio stops playing.

• Play Mode: By Order or Randomly
  Play broadcast shows episodes by order or in shuffle mode.

• Era-Specific Audio FX
  Instantly apply AM “static,” FM warmth, scratchy vintage vinyl cracks, or crystal-clear modern audio with a single setting in the Details panel.

• Audio FX debug widget
  Test and discover your own custom AM or FM radio sound effect by sliders at runtime to personalize your radio experience.  

• Automatic content detection
  The system will automatically detect what you have and not have put in the data asset. Meaning that fields that are empty will not be calculated into the system.

• Self-driven system
  The system is built to keep moving on when it's done with a whole broadcast show. It will find all unplayed shows that are available and then play the next.

• Prefab Blueprints Included
  Drag-and-drop ready radio setup blueprints into the scene—complete with era-accurate mesh, sound effects, and audio quality presets, choose eras between 1900s - 2020s

• Broadcast interruptions
  Random interruptions like weather alerts, breaking news, advertisements. Easy toggle on/off and adjustments in the details panel

• Runtime Controls
  Change channels and adjust volume at runtime—via widget or keybind—for fully interactive player experiences.

• Duplicate-safe playback
  The system tracks what’s currently playing and what has already played, so it won’t repeat the same song.

• Optimized system
  All functionality is driven from one master Blueprint paired with a single MetaSound master for ultra-lightweight performance.

• Clean, well-structured code
  The logic is 100% Blueprint, with an organized setup for fast, clear understanding and plenty of code comments

Package include:

• 1 Radio master Blueprint. (12 child blueprints).

• 7 radio controller interface widgets ( different styles based on era).

• 12 Data assets with audio content, like radio broadcast shows, weather reports, news, radio ads for each era from the 1900s - 2020s. (60s, 70s, 80s etc.)

• 100+ audio tracks (broadcast shows and music)

• Complete radio system meshes for each era
