Your best hope would be splitting it into 4 corners and making those 1000.25x1000.25 each I think (unless there’s some glitch to force it to be bigger that I don’t know about)
oh I know a way make 4 small squares each 1024*1024 then put the shape between it and negate it then union it all together then make multiple squares to fill the space and negate the outside (the bit you had left after the last negate) and union all together then you should be able to resize it if you dont know what I mean send the shape in a roblox file and ill make it the right size.
