Endless Grid in Scene View (Unity Editor), (w/ snapping)

Hi. Does anybody know how to make a custom endless grid in Unity’s scene view? I’ve been stuck on it for some time and I’m not sure how to approach it.

Something like this for reference:

Something along the line (pun intended :smile:) https://wiki.unity3d.com/index.php/DrawGizmoGrid

Appreciated, but do you know how to make it endless? Generally trying to make each tile interactable with it’s respected position, and I have a feeling it has got to do something with the user’s zoom level and screen size maybe?
