I mean you can create and sculpt but part about procedural creating and painting is not working
Please report issues with the plugin on its repository, not here.
I hope that this will change with Godot 4 because game engine without working terrein editor is a very bad idea and whole point of migration to Vulcan to make it a fast and good 3D game engine could be pointless
There will surely be at least one terrain plugin that will be ported to Godot 4.0. However, there are no plans to have built-in terrain support in Godot 4.0 due to time constraints. It may happen in a future 4.x release, but it's unfortunately not feasible for 4.0.
