Upload Demo App and Apply Pre-Made Patch
This guide walks you through the process of uploading a demo Unreal Engine application and applying a pre-made .pak patch using the Eagle 3D Streaming platform. This is ideal for understanding how patch functionality works—without needing to build a project from scratch.
Step 1. Download the demo packaged build from the link below:
Download Packaged Demo Project
Step 2. Go to Control Panel
Step 3. Upload the zip file downloaded in Step 1.
Refer to the official guide: Upload Your App
Step 4. Play the game
Follow Step 7 onwards from the below documentation: Stream Your App From Control Panel
Step 5. You should now see your app running in the browser.

The next step is to upload pak file
Step 6. Construct Patch Upload URL
Use this pattern to create the upload link:
https://upload-old.eagle3dstreaming.com/patch/{userName}/{appName}/latest{userName} → Your username on the https://controlpanel.eagle3dstreaming.com/
{appName} → The app name you used while uploading in Step 3
If your username is demo and your app name is patchDemo, your final URL will be:
https://upload-old.eagle3dstreaming.com/patch/demo/patchDemo/latest Step 7. Go to the URL you constructed above.

Step 8. Choose the Patch File
From the extracted contents of the .zip downloaded in Step 1, select the file:
Figure 3. Choose Pak File
Step 9. Upload the pak file

Step 10. Now Play the app again(like step 4)
Now return to your app and play it again (same as Step 4). You should now see the patch effects applied in the streamed app.
