Can you please give me some more details what you did, and what is not working any more? I assume you switched to engine version 4.19, but did you also update Physical Water Surface to the latest version? If you haven’t, I highly recommend you do this:
- Delete the old version of Physical Water Surface from your project, and make sure that all the deleted files are really gone by using the the file explorer of your operating system (the content browser in the engine sometimes doesn’t show all files).
- Right click in the content browser and migrate your project files to a new project. This step is optional, but it helped others who had similar problems.
- Add the newest version of Physical Water Surface again to your project.
Please let me know if this solved your problem.
