Oh, sorry, I misunderstood.
The extra version wouldn't work in “Tiled” because it comes with preconfigured resources, but only for Godot.
Right now it is not designed to perform autotiling (I don't know how it would work in "Tiled"), so there will probably be visual problems when creating the terrain, but...
You've given me the idea to include that feature, so I'm going to run some tests and try to add it to the package so that it works correctly with autotiling.
It might take a couple of days, but be prepared for an update. 👀
And thank you for your comment!
