How to Launch External Websites in Unreal Engine Pixel Streaming

Unreal Engine Pixel Streaming makes it possible to run high-fidelity Unreal Engine 5 applications directly in a web browser. From real estate virtual tours and digital twin streaming to gaming demos and enterprise training simulations, Pixel Streaming has become the go-to way for delivering immersive Unreal Engine experiences on the web.

But what happens when your users need to open an external website while exploring your Unreal Engine application in the browser?

• A buyer in a real estate walkthrough wants to view a PDF brochure.

• A trainee in a simulation clicks a button that should open a learning portal.

• A gamer in a browser-based Unreal multiplayer demo wants to jump to the leaderboard or Twitch stream.

  
  

Normally, in Unreal Engine you’d use the Launch URL node in Blueprints. But here’s the catch:

👉 In Pixel Streaming Unreal Engine 5, the application runs on a cloud server (AWS, Azure, Arcware, PureWeb, Eagle 3D Streaming, Streampixel, or your own on-prem Pixel Streaming server). The Launch URL node opens the browser on that remote server — not on the end-user’s device.

That means the link never reaches the person actually using the experience.

Why Standard Launch URL Fails in Pixel Streaming

• Traditional Unreal Engine workflow → Launch URL opens a web browser locally.

• Pixel Streaming Unreal workflow → Your app is running on a server (cloud or data center). The link opens on that server — invisible and useless to the end user.

  
  

This limitation affects multiple industries:

• Real Estate Pixel Streaming demos: users can’t access external documents or property links.

• Gaming & esports: leaderboards or tournament sites don’t load for the player.

• Training & enterprise simulations: links to manuals, LMS dashboards, or compliance resources are stuck in the server.

• Digital twin streaming: users can’t launch IoT dashboards or municipal portals from the 3D experience.

  
  

That’s a major roadblock if you want Unreal Engine web streaming to be fully interactive.

Streampixel’s Solution: Send Pixel Streaming Response

At Streampixel, we solved this by rethinking the workflow. Instead of trying to open a link on the GPU server, we send it through the Pixel Streaming WebRTC data channel straight to the browser frontend.

The solution is simple:

1. In Unreal Engine (Blueprint)

   • Add a button or interaction event in your UI.

   • Use the Send Pixel Streaming Response node instead of Launch URL.

   • Paste the url directly as it is.

     
     

   That’s it — the website opens directly in the end-user’s device browser, exactly where it belongs

   
   

   

   Using the Send Pixel Streaming Response node in Unreal Engine 5 to pass a URL to the frontend, allowing external websites to open directly in the user’s browser during Pixel Streaming.

Example Use Cases

This Unreal Engine Pixel Streaming integration unlocks countless workflows:

• 🏠 Real Estate Pixel Streaming → open floor plans, mortgage calculators, property PDFs.

• 🎮 Unreal Engine multiplayer in browser → link to esports brackets, Twitch streams, Discord servers.

• 🏭 Enterprise Training → redirect to LMS quizzes, safety manuals, or certification exams.

• 🌆 Smart Cities & Digital Twin Streaming → open dashboards, IoT control panels, or municipal reports.

• 💼 Enterprise Sales Demos → direct prospects to landing pages, signup forms, or product docs.

  
  

Why This Matters for Pixel Streaming Developers

Opening external links may sound like a small feature, but in practice it transforms Unreal Engine on browser into a true web-connected platform:

• Marketing & Sales → users can instantly jump from the immersive 3D demo to external sales material.

• User Engagement → let players or visitors share, learn, and interact beyond the 3D scene.

• Documentation & Compliance → integrate with enterprise workflows by linking manuals, policies, and portals.

• Cross-platform Pixel Streaming service → create hybrid user flows where Unreal connects seamlessly with web apps.

  
  

Instead of being locked inside a 3D stream, users can explore a fully interactive Unreal Engine web experience.

Conclusion

The Launch URL node in Unreal Engine doesn’t work for Pixel Streaming — it opens links on the cloud server instead of the user’s browser.
