Before upgrading a project, please make a backup of your working project.
To upgrade the Predictive Suite package in one of your projects, you only need to import the new package. New updates are released regularly and can be downloaded from your online account space. If you encounter errors after the reload, try the following : delete the "Assets/UVR" folder and reload the new package.
When upgrading or downgrading from a version to another, it is possible that some of your scenes refer to old scripts that were modified and lost. You can identify those missing scripts using the menu "PredictSuite/Package Update/Select GameObjecs With Missing Scripts".
If there are missing script references in some of your scenes, you can try to get them back by calling the menu "PredictSuite/Package Update/Update script references for current context".
If the missing references remain, you can always come back to your previous version and they should be placed back.
If you are having trouble while updating your project, please contact us and we'll provide you with some help.
