Hey, this grid floor is the one you see in the 3d viewport.
if you go to top/front/side view, the same grid floor will apare across the entire screen.
the amount of subdivisions determin how many divisions it will subdivide the grid floor when you zoom close enough inn. (see images down below)
The two following images are taken in side view in the view port. if i scroll one step closer, it will divide the whole thing.
this is something i find very frustrating, is there a way to change color on the subdivided grid, or disable it all together?
if i turn the amount of subdivisions down in the grid floor i get what i want in sideview, however that also removes the grid floor in the 3D view. i want to keep in in the 3D view, but remove it in 2D view.
