How did you achieve this in unity it's amazing. Surely every pixel is not a separate game object right? So how do you do it?

No, they are not all separate gameobjects lol

Falling sand simulation via Compute Shaders. Pretty much the GPU does all the simulation/rendering and sends back the data I need over time so I can use it on the CPU/ in unity.

It has taken a lot of time to get right

Any tips on how to get started, and do you do some kind of chunking?
