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
- 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.
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.
