Flexible Glass is a URP UGUI liquid glass solution where:
-
Glass panels can smoothly combine and subtract
-
Glass panels can be defined with sprite shape (so long as the sprite is a ~reasonable resolution, perimeter will be smooth and high-res)
-
The effect actually looks really good
I believe otherwise you may get one-and-a-half of those 
FG is also very customizeable, especially when it comes to “edge lighting”
It has a built-in blur system that is actually quite good, but also has Flexible Blur integration for even better blur.
FG is included in the Flexible UI Suite.
