How to make border looks irregular just like the one from Civ6 strategic view?

[hotairlol]

I have been working on generating a world map using some hex tiles. It ends up looking like this:

(capture from Sid Meier’s Civilization V)

It doesn’t feel like a “map”, so I wonder is there are any tips or guides for making a more realistic map?

(This capture from Sid Meier’s Civilization VI, this one uses regular hex tile but is a bit better than the one from Civ5, but I can’t tell the differences…)

and

(also from Sid Meier’s Civilization VI, I wonder how they make the border look “irregular”, is that because of material? I can’t find any related Unity guides to recreate this.)

you could probably do this with a shader, calculate noise based on 2d position to modulate alpha of your tiles. you could probably use a noise texture as well, though at a decent resolution (256x256 or higher) so tiling isn’t obvious

Thanks for the reply! I have never used shader or noise texture before so I am not sure how they work, especially in this case. Do you have any related guides or tutorials for this?

here’s a video that’s sort of related if you’d like to use shader graph.

at that point you can just consider it a different implementation of tilemaps that is not available by default in unity

its just puzzle pieces that fit into eachother, or just plain overlap that makes it look like they fit together, anyway for this style i dont believe that you could use unity tilemaps feature to achieve it, or it would be more effort than its worth
