Physics and other areas are tuned for this scale. Therefore, attempting to use a
different scale is usually a bad idea (unless you know what you are doing).

When working with 3D assets, it's always best to work in the correct
scale (set your DCC to metric). Godot allows scaling post-import and,
while this works in most cases, in rare situations it may introduce
floating-point precision issues (and thus, glitches or artifacts) in
delicate areas, such as rendering or physics, so make sure your artists
