Needle Cloud update link

🌵 Needle Engine

I want to ask, if when I make some changes in my Unity scene and upload then the new version with updated on Needle Cloud. Does it generates a new link. My goal is to have a QR code and it is linked to the Needle Cloud website and if I make any changes to the Needle cloud they are made to the same link and not a new link is generated everytime for new uploads from Unity.

Hi Samsmeep!

Plan in Pseudocode:

  1. Clarify what happens when a Unity project is uploaded to Needle Cloud.
  2. Explain if uploading a new version creates a new link or keeps the same one.
  3. Provide advice on QR code stability for project updates.

Explanation:

When you update your Unity scene and upload it to Needle Cloud using the Needle Engine exporter, you generally have two options:

  • Update the existing project: This will overwrite the existing build with your new changes while keeping the same URL. Your QR code or existing link will always point to the latest version.
  • Create a new project: This generates a completely new link/URL for your project.

For your use-case (stable QR code), make sure that each time you upload, you are pushing an update to the same Needle Cloud project (not creating a new project each time). The URL and thus the QR code remain unchanged. You can safely distribute your QR code, and all future updates will go live at the same link.

How to ensure this:

  • In the Needle Engine export window in Unity, select your existing Needle Cloud project before hitting upload.
  • Don’t use “Create New Project”.

Tip:
If you’re unsure, check in the exporter dialog: it should show your existing project. You can always test your QR code after an update to verify!

How to ask good questions:

  • Specify your engine and version (e.g., Unity 2021, Needle Engine version).
  • Describe your current workflow or problem step by step.
  • Include links or screenshots for clarity.

Hi, for that you can assign a URL label - either one that is automatically update ( latest) or one that you can update in Needle Cloud manually.

Then just copy the appropriate label URL

Please see the docs for details: Needle Cloud | Needle Engine Documentation

Actually I am having an issue, so to test it I had on my 1st upload my 3d model under tag Untagged where it shows in the web browser and then in the second upload on the cloud I had the 3d model tagged as EditorOnly. As soon as it finished uploading to cloud the website opens and one sees that the 3d model is not there but when I press on the latest button on Needle Cloud and try to open the latest scene where no 3d Model should be there it still shows me the 1st upload on the latest link.

When opening the same URL for the second time after a short amount of time you might see the client-side browser cache.

Try reloading your website with a hard refresh or clear your browser cache to force the browser to download the content again.

Hi, I just wanted to follow-up and let you know that this has been improved now and updates to the labels on Needle Cloud (e.g. when you update the ‘main’ label) should now generally reflect faster in your browser, even after the site is already cached locally.
