I appreciate your work, author of the NavigationRegion3D node, I really do... but can you please not be so opinionated about how much floating point precision you think people need? So much so that you even override the user's floating point precision settings to round numbers up to 2 decimal places?
I can't even set the cell size to 1/8th or 1/16th, without this tool rounding cells up to an irregular value that creates all kinds of artifacting and errors in the navmesh of my otherwise nice, orderly grid tiles.
I'm about to just write my own navmesh editor, I swear...
