I am working on isometric tilemap in Unity 2019.4.8f1.
In the Tile Palette panel, the selection is always 1 block away. Please see this screenshot:
In the screenshot, apparently I selected an empty tile, but in fact I am select the green tile with flowers. How come? Every selection is one tile away. The same issue happens in the Tilemap selection mode too. I have to select the adjacent tile in order to select the tile I want.
How do I fix it? It's quite annoying.
UPDATE I have added the settings of Grid, Tilemap as well as the import settings of the tile sprite sheet below.
UPDATE 2 Changed the Pivot in Sprite Editor to Bottom Center
Recreated the Tile Palette, and it looks like hovering 0.5 unit up.
