I’m trying to add a normal map to an autotile tileset. This answer
https://forum.godotengine.org/82555/normal-map-for-tileset?show=82555#q82555
says “If you use autotile, you just need to set the complete normal map once.”

I understand to create a normal map of this region:

And add this normal map to the Normal Map property of the region:

But this does not work – the selected normal map sprites do not fit the autotile sprites (light from lower left):

How should the normal map sprite look like?

Figured it out on my own. The normal map needs to correspond to the whole sprite sheet, not just the region that it is for. And, of course, the normal map region needs to correspond to the sprite sheet region that it is for.
