Protecting 3D models

Hello everyone, I have a question regarding the security of my loaded 3d models.

When a .glb file is used in a hosted babylon environment, is it possible for people to rip that file out of memory? If so, are there any common practices to keep your files safe?

Apologies if this is a common/simple question, I am rather new to Babylon.js

My understanding is that anything that is displayed in the browser as a 3D model can be ripped out of memory.

one straightforward way I can think of is to render on the server and stream the content.

here’s a prior discussion on it.

but yeah as Anderson said, if it’s sent to the browser it’s trivial to rip it.

You could encrypt the files you are loading, but this only protects them from being ripped directly. Once its loaded into memory a determined enough user can always get at the data and thats not just a web problem.

It is indeed possible for people to extract or “rip” 3D models, including .glb files, from a hosted Babylon.js environment or any other client-side rendered application. Since the browser needs to download and parse the model to render it, a determined individual with sufficient technical knowledge can access and save the model by using browser development tools or network monitoring tools.

There are a few approaches to help protect your 3D models, although none of them are completely foolproof:

  1. Server-side rendering: By rendering the 3D scene on the server and streaming images or video to the client, you can prevent direct access to your models. However, this requires significant server resources and introduces latency.

  2. Obfuscation: You can make it more difficult for users to access your models by obfuscating or encrypting the data. This involves transforming your model data in a way that makes it harder to understand or parse without authorization. Keep in mind that this may not prevent experienced individuals from eventually extracting the model.

  3. Watermarking: Adding a visible or invisible watermark to your models can help identify unauthorized usage or discourage users from sharing your content without permission. This can be done by embedding a specific pattern or data within the model itself.

  4. Access control and user authentication: Implementing authentication and access control measures on your website can help limit unauthorized access to your 3D models. This can include requiring users to log in before being able to view the models, restricting access to specific IP addresses, or employing other access control measures.

Ultimately, it’s important to understand that once the 3D model is sent to the client-side for rendering, it’s challenging to completely prevent users from accessing and extracting it. The best approach is to implement a combination of the techniques mentioned above and continuously monitor for unauthorized usage of your models.


Probably you may calculate how much you may lose if somebody will get your model and how much you will spend to some “defense system”.
From my point of view, one needs to rely upon common copyright laws, which are designed to protect intellectual property.

I’ll mark this as the solution as it gives the best information, thank you everyone!
