Encrypting my files.
Can’t get it worked.
I followed the instructions on Making a Demo in the RF manual.
After making sure the game ran fine using RFeditPro. I then use RFvfs to add all the files, and save them to a pack.vfs file. To my delight, the game ran fine! I have just one problem. When I saved the vfs file, I checked the encryption button, but I am still seeing all my files as they were before. They didn’t seem to encrypt. Any idea what happened?
Also I get an error when I try to make a prefab (Error writing object to file). I select an act object used as a StaticEntityProxy, and select “New Prefab brush” from the tools bar. Am I doing something wrong?
Thanks

Of course the encryption works. If someone wants to open the files, they will just see some gibberish thinghs like many black boxes.

That's the thing. I opened the files, and there are clearly the same as before.
