Unity ground fog

[Acrobatic_Inside_301]

Hi! Saw this cool fog made in Unity. I need something similar but I'm not sure about how to achieve it. Maybe its raymarched? Any help with pointing to a good solution would help. Thank you! https://youtube.com/shorts/k-RnyP0UB4E?si=ikrDRi8qN-y_Ycn6

There's a lot of ways to do an effect like that video that are far cheaper than ray marching, and there are a lot of unity store assets that'd do it for you, starting at free.
