Revision history#

Migrating your project from MiddleVR 2.5 to MiddleVR 3.0#

Note: You don't need to install MiddleVR 3.0 on all your cluster clients. You only need to install it on your cluster server and on your development computers.

On opening your projects after installing MiddleVR 3.0 you might get the following error: Failed to resolve packages: Tarball package [com.middlevr] cannot be found...

You can either continue and load the new packages from the Package Manager from C:/Program Files/MiddleVR3/unity_packages or modify the file Packages\manifest.json and change the line:

"com.middlevr": "file:C:/Program Files/MiddleVR2/unity_packages/com.middlevr.tgz",

to:

"com.middlevr": "file:C:/Program Files/MiddleVR3/unity_packages/com.middlevr.tgz",

Do the same for all the MiddleVR packages your project uses.

You can then click Retry or Quit and reload the project.

  • If needed, delete and re-import the MVRManager.

  • URP: On the MVR_URP GameObject, remove script 'URPSettings' and add script Packages/MiddleVR URP/Runtime/MVR_URPSettings instead.

MiddleVR 3.0.3#
