Hi @vlad3r08 ,
I understand you can’t install it in 4.24, I have not yet tried to do that as I am currently on 4.22. You can install 4.23 and install the plugin and get the source in the following folder: On a standard windows install: ProgramFiles\EpicGames\UE version\Engine\Plugins\Marketplace\DonAINavigation.
