Hey yes, this plugin is still in development. Thanks for the discord idea, I’ll consider it.
Regarding your question, yes this plugin has the landscape brush system implemented for UEv4.24-4.27, although there are some issues in UEv5.xxx.
For UEv4.27-5.xxx I would recommend using the “Deform andscape” functionto to deform the landscape as it now supports the landscape layer system and you can set a specific layer to deform.
