Welcome to TVPaint Community forums !

The images created by the Repeated Images feature don't get proberly exported if you use the JSON export and since I couldn't find an option to apply this images I wrote a script for it
It creates a duplicate layer, clears it and than merges it with the original layer.

I can see myself using this a lot, thanks so much!

You're welcome. I'm always happy if someone finds use for it too

Thanks
