Hi,
I made this in Blender, dots on a plane that are affected by light (sun), shading is also visible here (some dots are less visible - shadow), it also behaves like ocean. How would I achieve the same effect in Unity that is not performance heavy?
The most trivial solution that comes to my mind is to use a subdivided plane with enough vertices and to use a texture with a dot that is mapped to each quad on the mesh. It is technically not sophisticated and more fake, but it gets you the dots, filtering, shadow, fog, and everything else that URP offers.
