Max Union Size Help need

Union Size.
I’ve been trying to make an island as big as possible but the max I could of gotten was (underneath)
The max size for a Union is 2048,2048,2048.
Anyone has any other ways?

Yea, by not using Unions.

Making an entire island a single Union isn’t really wise. It’d have terrible collisions, and just generally is a bad way to do that. Just make it out of multiple Parts.

Besides, the max object side for any 3D object is 2048x2048x2048, so you’re going to need multiple pieces anyways.
