¶ Licensing
The Volinga Plugin for Unreal Engine uses an asset-based licensing system that directly controls watermark visibility.
When you import and render NVOL files, the presence of a watermark depends on whether the asset was created with a Volinga Suite license that includes commercial usage rights. Assets without a valid commercial license will display a watermark in the viewport.
Please note: Any Unreal Engine scene containing one or more unlicensed assets—in either NVOL or PLY format—will display a watermark across the entire viewport.
For completely watermark-free rendering, every asset in the scene must be properly licensed according to its specific requirements.
- To obtain your license, you must first sign in to the Volinga website.
-
After logging in, you will be able to see the available product options.
You can start a free trial or purchase the version that best fits your requirements. -
To activate your license, you must obtain the hardware hash of the machine where the plugin will be used (see License Considerations below).
¶ How to Obtain the Hardware Hash
To retrieve your hardware hash, please follow the tutorial corresponding to the plugin version you are using:
¶ How to Generate a License File
-
Once the hardware hash for the target machine has been retrieved, click the “Download License” button for the desired license.
-
The first time you do this, a dialog will appear requesting the hardware hash.
-
After entering the hash and clicking “Generate”, a new license file will be created.
-
On subsequent clicks of the “Download License” button, the system will directly download the previously generated license file.
¶ License Considerations
- Licenses are bound to a single machine.
- If you change devices, you must generate a new license.
- If you generate the license on a different machine than the one running the plugin, the license will not work.
- Some users generate licenses with an incorrect or missing hardware hash. Always verify that your license is associated with the correct hash.
- Hardware changes (new hard drive, network card, VPN virtual interfaces) may alter the hardware hash and invalidate the license.
- Ensure that your license is valid and not expired. Loading NVOL files with an expired license will display a watermark, even if no warning message appears.
¶ Common Watermark Issues
Here are some common Watermark issues users might encounter with the Volinga Plugin.
¶ Additional Considerations Before Reporting an Issue
¶ Possible corruption of DefaultVolingaRenderer.ini (ver 0.7.x)
- Close your Unreal Engine project
- Delete the file: [project folder]/Config/DefaultVolingaRenderer.ini
- Reopen the project
- Reload your license via: Edit → Project Settings → Volinga → License
¶ Use of Pro features with a Basic or Trial license
- Cull Volume, Proxy Mesh Lighting, and nDisplay are Pro-only features.
- Using them with a Basic or Trial license will:
- Display a watermark
- Limit functionality
- Potentially trigger an automatic plugin notification
¶ NVOL and PLY generation
- Test different NVOL and PLY files to see if the watermark issue persists.
- If the watermark fades in/out, it may be related to a problem in the asset generation method.

Affected Features: Cull Volume, Proxy Mesh, nDisplay, etc.
Solution: Upgrade to Plugin Pro.
Watermark appears after packaging project to another machine
Cause: License is bound per device.
Solution: Activate on the new system or request a multi-machine license.
