No plans to do a follow up training stream right now though it does seem like a good idea to do a follow up as honestly a lot of stuff in the video is moderately to severely out of date now with Editor Utility Widgets and better ways to script the editor in python and BPs. There’s some cool stuff coming as well for menu extension that makes it way easier than so you don’t have to mess about with FExtender anymore.
The project was originally supposed to be posted on the launcher but it never made it up for one reason or another. I’m going to attach it , but I haven’t touched the sample since the training stream so it’s circa 4.6, caveat emptor. You can find similar examples of a lot of plugin extension techniques in the Paper2D plugin as well, though it hasn’t yet been updated to take advantage of the new menu extension stuff, etc… yet even @head.
Cheers,
