Hi,
I've been playing today with water have built a pool which I'm trying to fill. Only tool I know to use is the [F5]terrain tool which isn't very good get blotchy water. I think the Lus script using /we Select then /we fill or /we place might be easier to use Is that possible. What is the name and iid of water please.
It's recommendable to enable the height limitation (return key, and pgup/pgdown to adjust the height) for the water tool, this way you get smooth water surfaces If you want to fill a pool for example, it's eventually also easier to use the rectangular shape (enable it by pressing G).
However, the water IDs are 100 and 101 (saltwater)
