MRTK2 configuration dialog

The MRTK configuration dialog is displayed when Unity loads a project and it is determined that one or more configuration options needs the attention of the developer.

Apply Later Ignore

To apply the changes, click the Apply button. The Later button will defer the changes until the project is reloaded at a future time.


The configuration dialog will reappear if one or more of the recommended settings is left unchecked. To prevent this from occurring, apply the desired options, then relaunch the dialog via Mixed Reality Toolkit > Utilities > Configure Unity Project and click Ignore. This will prevent the configuration dialog from reappearing automatically.
