| Dec 15, 2019 at 18:03 | comment | added | WDUK | Engine doesn't support doubles as the graphics pipeline doesn't accept values that are doubles, ask the Unity devs on why as i do not know. Regarding your second point, i don't know the answer but many people have implemented grids that are not 1 by 1 and snapped precisely to the integer coordinates so it must be doable. | |
