Water

Smooth Terrain water prior to the 2024 update.

This audio is played upon collision with the water terrain material. This file is called "impact_water.mp3" in Roblox files.

The sound that plays when a player swims in water.

Terrain Water is a type of material in Terrain. It is mainly used to form oceans, lakes, ponds, or waterfalls, or installed in pools and water fountains. It can be used in boat ride games or decoration in Personal Servers. Water is used in the Terrain Generator script plugin as the ocean and lake filling. Terrain water is used in some games as it is easier using terrain water than scripting custom water.

The new smooth terrain water is not cubic but instead much smoother, as the name indicates. Updates allowed the color of the water to be adjusted as well.

Water does not consume air or cause damage by swimming in it for too long by default. Scripts are required to implement this.

In the 2024 "Shorelines" update, the smooth terrain water was updated to be a cell separated from the main terrain materials, allowing for water to not merge into the main terrain and the shorelines to rise and fall like the main water. Formerly, smooth water would rise mainly in the middle, and hardly on shorelines. The rising on shorelines could cause a crack to show in between the terrain and the water, this has also been fixed with the "Shorelines" update by stretching the water geometry past the terrain.

Physics

Buoyancy

Players can swim in the water unless they are wearing too many accessories. Wearing no accessories allows players to automatically float upwards. 1 accessory will slowly sink the character and resistance when swimming upwards begins. Wearing any more accessories will make it more difficult to swim upwards (without jumping). Ironically, accessories will easily float on water by themselves.

Parts made from the following materials will float on water by default:

• Fabric
• Glacier
• Grass
• Ground
• Ice
• Leafy Grass
• Neon
• Plastic
• Smooth Plastic
• Wood
• Wood Planks

Other materials will not, just like in real life. However, attaching parts made with any of the above materials will allow non-buoyant parts to float.

Properties

Water properties can be found and edited under the Terrain class.

WaterColor

Water with its color changed to purple.

Changes the color of the water. This affects the entire game. The default color is (12, 84, 92).

WaterTransparency

Water with its transparency increased.

Increases or decreases the transparency of the water. 0 is completely opaque, while 1 is transparent.

NOTE: If the player's graphics settings are below 8, this will only be seen when underwater.

WaterWaveSize

Increases the height of waves. 0 makes waves non-existent and 1 is the highest possible.

NOTE: Lowering you graphics settings down to 2 or lower will get rid of any waves on your screen, regardless of the actual games' settings.

WaterWaveSpeed

Increases the speed of waves. The range is from 0 (water is completely static) to 100 (water moves at 100 studs/second).

Trivia

• Like other Terrain materials, exploits can be used to ruin places, by flooding the place.
• Putting the camera in the water right on the edge of the air will cause the sky to turn as if it were night. This bug has not been resolved yet.
