Water Level

The Water Level (ie height) simulation can simulate water bodies of varied height and tides. The default water level is sea level, which is the height of the Water Renderer.

Tides

It is possible to move the entire water surface on the Y axis to simulate tides. The Water Level simulation can be used to localize the tide.

User Inputs

Geometry

Sets the water level using the provided geometry.

See Geometry Mode for more.

Spline

The spline input mode will use the spline mesh to set the water level.

See Spline Mode for more.

Paint

The paint input mode will enable paint tools to paint add/set the water level.

The water level can be raised or lowered with LeftClick and Control-LeftClick respectively. Use Shift-LeftClick to remove water level.

See Paint Mode for more.

Texture

Set water level using a height map.

See Texture Mode for more.

Renderer

Set the water level using a mesh using the Water Level From Geometry material.

See Renderer Mode for more.

Troubleshooting

There is staircasing and/or small bumps on the water surface

This is due to lack of precision. Set Water Renderer ‣ Simulations ‣ Animated Waves ‣ Texture Format Mode to Precision, and set Water Renderer ‣ Simulations ‣ Water Level ‣ Texture Format Mode to Automatic.

If the problem persists, and you are targetting a mobile platform, then enable Project Settings ‣ Crest ‣ Full Precision Displacement On Half Precision Platforms.
