Hey veer… thanks for the kind words. Really glad u like the work.
About the file you shared, I checked it seems like you are using an older version of Controller Plugin, this wouldn’t cause any problems, but it is always good to be on the latest version.
I was going to get in contact with you about the latest plugin… Basically It would not work, so reverted back to a previous version I had used in some other tests here. As I’m not sure how to easily debug this, all I can say is that the plugin runs, but gives no results, no controller etc. I tried it on a few Debian based Linux machines here all running different versions of Synfig… 1.4.2, 1.4.4, and 1.5.1 dev build.Python 3.8.10 - 3.11.1. All ran the version from Febuary '22 but no joy with latest.
