Apologies…my dropbox links dropped out.
Here are the updated files:

This has not been tested with the latest version. I bought 6 different types of mirrors (glass and acrylic) and couldn’t find what i was looking for so gave up the dream for now…

So I ran into this problem and have a fix. I have uploaded the files to drop box for know. If this fixes others, i’ll look into updating the project.

There are 2 files that need updated:
