Same . Many questions on thread and 99% of them never has an answer.
plugin is one of the most expensive of the UE4 market and is just NOT production ready as too many things just don’t work/lack support and updates.
It looks like the creator has left the boat and the plugin is maintenained by someone else (michael_simul) but doesn’t have much time.
Guys, if you can’t/don’t have time to make a plugin usable in a commercial projet, just don’t sell it as all you do is making people waste time/money.
