How do I autotile this?

Godot Version

Question

I am new to autotiling and can’t seem to understand how to configure the bitmap to autotile the rest of this. Some help would be greatly appreciated!

I assume that you have two types of grass, light grass and dark grass? Add a new element (new terrain) to your terrain set. Let’s call the existing terrain Light Grass and the new terrain Dark Grass. Paint the dark grass tiles with Dark Grass terrain like you have done with the light grass tiles. If you want the textures to connect automatically, paint all empty regions of the light grass tiles with Dark Grass terrain. Then paint all empty regions of the dark grass tiles with Light Grass terrain.

Hi,
It is actually the same type of tile (bush tile) and the ones below are supposed to be for the inside of the bush while the ones above are supposed to be for the edges. So they should connect to each other in a certain type of way, but I am clueless on how to accomplish this with the bitmap.

Maybe like this?

Paint the inside tiles with different terrain the same way you painted the edge tiles. Then paint empty regions of inside tiles with the edge tile terrain.

Example:

Orange: edge terrain
Dark red: inside terrain
