Troubleshooting the watermark

If a running application displays a watermark "Powered by MiddleVR", there are several things to watch out.

Any application exported from a computer with the following MiddleVR editions (MiddleVR Free edition, MiddleVR Trial edition or temporary license (HMD / Pro / Academic) will display a watermark even if the computer running the application has a valid license.

 

If you have exported your application from a computer with a valid license, please send to the support team the following logs:

- Open Unity and re-export your application. Then send the resulting MiddleVR_UnityEditor_Log.txt.

- Run the application, then send the resulting MiddleVR_UnityPlayer_Log.txt

 

More details:

- With MiddleVR HMD edition you can export an application that will run on computers without a valid license. You should not have the watermark as long as the HMD license is a permanent one AND your configuration file does not exceed the capabilities of the HMD edition. See the products comparison chart.

- With MiddleVR Academic edition you can export an application that will run on computers without a valid license as long as the configuration does not use cluster or multi-GPU.

- With MiddleVR Pro edition you can export an application that will run on computers without a valid license as long as the Pro license is a permanent one AND your configuration file does not exceed the capabilities of the HMD edition. See the products comparison chart. For any other usage, especially Active Stereo (OpenGL Quad-Buffer), Cluster or Multi-GPU, you wil need one license per computer/GPU.

More troubleshooting

If you have exported your application with a valid license and you still have the watermark, the following can occur:

- At build time, MiddleVR creates a "mvr.sig" file in the _Data/ folder of the built application. Make sure this file is here.

- This file is a signature file based on some files in the _Data/ folder. Make sure nothing in this folder is changed, added or removed during or after export.

- Instead of overwriting the build, completely deleted it.

- Changed the location of where you build.

- Cleared the registry values for the build.

- Make sure the application is not build with "Development Build"

- A client reports that "AmplifyTexture plugin(virtual texturing) conflicts with the licensing mechanisme of MiddleVR.

- Another client reports that if the application is built in a Git folder, the licensing mechanism also fails. Simply export the application in a folder that is not in Git.
