🎵 Patchwork Parkour (Island Code: 1425-4464-4801) is a music-driven platformer developed by Look North World in collaboration with Harmonix Labs, a division of Epic Games known for its world-class rhythm-based experiences.

This innovative Fortnite Creative island showcases the power of Patchwork, a UEFN toolset designed for interactive, music-driven gameplay.

How Patchwork Parkour Creates Rhythm-Based Gameplay

Patchwork Parkour syncs gameplay with music using three key Patchwork components:

🎼 Note Sequencer – Plays notes in time with the set tempo.
🎯 Note Trigger – Fires events when specific notes are played.
🔄 Song Sync – Synchronizes UEFN Level Sequences with audio.

🔹 How It Works: Developers used these tools to animate obstacles, hazards, and level changes in perfect sync with the soundtrack, enhancing both challenge and immersion.

Building a Dynamic Soundtrack in Fortnite UEFN

With Patchwork’s advanced audio tools, Look North World blended internally generated sounds and external samples into a seamless soundtrack.

🎧 Key Sound Design Components Used:

✔️ Fusion Patches – Integrated custom samples from external audio tools.
✔️ Instrument Players, Effects & Modulators – Added depth and complexity to the sound.
✔️ Music Manager – Maintained precise tempo control, ensuring all elements remained in sync.

🔹 Why It Matters: This method allowed for layered, evolving audio while reducing the number of active devices, keeping performance smooth and optimized.

How Gameplay Affects Music in Patchwork Parkour

To create an interactive music experience, developers introduced real-time audio changes based on player actions.

🔹 Key Features:

✅ Mutator Zones – Activates Patchwork devices based on player movement.
✅ Patchwork Value Setter – Adjusts music dynamically based on triggers.
✅ Note Sequencers with Multiple Pages – Enables seamless transitions between music sections as players progress.

🎶 The Result: A dynamic soundtrack that evolves based on player movement, making every session unique!

Optimizing Performance & Reducing Memory Usage

Since Patchwork devices can be memory-intensive, developers implemented several optimizations:

🛠️ Patchwork Memory Mode – Disabled unnecessary animations to free up resources.
🔄 Multiple Pages in Note Sequencers – Minimized active devices.
🎼 Fusion Samples – Reduced device usage by integrating pre-mixed audio from external tools.

📉 Additional Optimizations:

✔️ Consolidated Cinematic Sequence Devices to reduce performance impact.
✔️ Minimized Skeletal Mesh usage to improve game performance.

Lessons Learned & Development Tips

💡 Best practices when building rhythm-based gameplay in Fortnite UEFN:

✔️ Use Patchwork Memory Mode for better optimization.
✔️ Leverage Fusion Samples to balance audio complexity & performance.
✔️ Avoid skeletal meshes in cinematics where possible.
✔️ Bind only one actor per transform track to improve sequence efficiency.
✔️ Use Value Setters to create interactive, dynamic music.
