What is the maximum size terrain allowed to be published?

Hi,

I’m just wondering what the maximum size terrain is for ROBLOX servers to allow, I attempted to create a 15000x1000x15000 terrain to see if that would publish, left ROBLOX to generate the terrain, and then when I tried to publish it wouldn’t allow me to? I’m assuming theres a limit and if possible does anyone know what it is?

Thanks,

probably not an intentional limitation, i guess it’s too big for the engine itself, I doubt anyone knows the limit
