2D Fog of War

Hope this is the correct section.

So I am using 2 Circles as masks on my Dark and Semi Dark Tile Map for fog. As below is my results. I like the look.

I am trying to make it look similar to this. What I noticed is that the style is the same. Look like they are USing Metaballs technique but this is where I fail. I have tried so many tutorials on it but can never get one that is using URP.

DESIRED LOOK!

Any help on this would be great!!!

Got it. Will polish it but man Happy with what I am Seeing!

Every Light has a shimmer effect to it.

Any chance you would share your technique?
