This happened today, and my game is a lot laggier. How do I remove it?

Can you provide screenshots? Then we could address the problem better.

Sorry, it didn’t show up. Here’s the edit.

[M_caw (Macaw)]

Simply use the sea level feature. Wrap the box around the water and press evaporate. It’s very quick and efficient. Find it under edit in the terrain editor.
No need to manually remove the water with subtract-

[SystemSoftware1 (System)]

Open Terrain editor and find subtract and click Ignore Water (turn it off) and remove the water manually.

the box is too small to select all of the water.

Really? You can change how large it is. It can go up to 16384x16384 studs. That’s 500x500 baseplates.

Change Base Size. It should work

Rip performance

There is no base size for sea level, it’s not a brush. You can only extend and retract the sides, like resizing a part.
And the maximum sea level can go is the maximum terrain generation can go, 16384x16384.

It may take awhile but it should work (if it did plz mark as solution)
