Why we should just have waterparts[/quote]
You can set the part’s material to water via part.Material = Enum.Material.Water but it turns invisible (and probably uncancollidable). I wonder if this will ever change in the future…?
I doubt it – the reason terrain is able to function smoothly (namely water) is because it works on a voxel system. I know it’s extremely annoying to have to move your entire map up/down/left/right just to get the water to fit in canals, pools, etc / terrain not being able to be copy/pasted/saved with a model, but I guess that’s just something we’ll have to live with.
