The water terrain is not appearing when being too far. I also have Graphic Quality set to maximum and have maximum Quality Level & Edit Quality Level
Does anybody know how could I fix this?
Not sure because I did not have that problem when I did that. Tell me how big the water is so I can better test and help you.
I used Terrain:FillBlock with a part which has the size of Vector3 (1007.917, 3.528, 967.6)
I spawned in a chunk of water the size of (1007.917, 3.528, 967.6) like you said and I did not have those problems.
Will try to recover the water terrain with fake water I guess
Ok also this may be happening to prevent lag (Roblox is doing this) because from the video it looks like its a big map
