I'm working on a Unity 3D game that requires fog of war. It is seen from above. I was looking for help and found this: (I dont know what game it is though)

This would perfectly fit my needs but I don't know how to do it. I created a grid of flat hexagons and tried applying shaders but the results are not satisfying. If we look at the image, we can see that the clouds are made of hexagons tiles too and the texture blend with the neighbouring tiles without seams.

My needs are:

• Clouds can be tiled so that I can remove them as the player explore the world
• Texture blends with it's neighbours
• Texture tiling is non-existant or not obvious
• Animated
• Opaque (I don't want the player to be able to see through it)

I'm literally trying to do the exact same thing as the GIF. For info, I'm using URP.

Any help or clues would be very appreciated.
