Specifies how deep the water volume should be.
Specifies at which speed the water should be moving. Not used for water volumes, inherited from Area Shapes.
Specifies the density of the fog.
Lets you choose the underwater fog color.
Fog Color Multiplier
Lets you choose how bright the underwater fog color is.
Fog Color Affected By Sun
If true, Sun Color value set in the Environment Editor will affect fog color of the water volume.
If enabled, the surface of the water volume will receive shadows. You can control the shadow darkness, valid input 0-1.
NOTE: r_FogShadowsWater needs to be set to '1' for this to function, which is currently only enabled on Very High Spec.
Cap Fog At Volume Depth
If false, fog will continue to render below the specified Depth of water volume.
Specifies how much the water surface (bump) texture is tiled horizontally.
Specifies how much the water surface (bump) texture is tiled vertically.
Enables Caustics for this entity.
Controls the intensity of the caustics (this scales the normals of the surface when rendering to the caustic map, producing stronger caustics).
This is a multiplier for the tiling applied to the surface normals during caustic generation. It allows you to scale the caustics generation independently from the surface material in cases of strong tiled normals or vice-versa.
Controls the height above the water entity in which caustics can be cast. This can be used to cause caustics on overhangs and other nearby objects.
Will trace a ray down from the volume's initial shape's center to find a 'vessel' entity and 'spill' the requested amount of water into it. For static entities, it'll try to boolean-merge any surrounding static that intersects with the first vessel (use "No Dynamic Water" flag on brushes that don't need that). Volume's shape will then be adjusted dynamically to match the vessel's geometry.
Water level will be calculated until the resulting volume is within this (relative) difference from the target volume (if it's set to 0 it'll run up to a hardcoded iteration limit).
Will extrude the border by this distance. It's particularly useful if wave sim in on since waves can raise the surface and thus reveal open edges if they lie exactly on the vessel geometry.
Will take convex hull of the border. Mainly useful if the border would otherwise have multiple contours, which areas don't support.
Object Size Limit
The Only object that has volume larger than this will take part in water displacement (set in fractions of FixedVolume).
Wave Sim Cell
Size of a cell for wave simulation (0 means no waves). Can be enabled regardless of whether FixedVolume is used or not. Use smaller sizes like 0.05-0.2m to have enough details on smaller volumes, and larger ones if you need to fill a large vessel/area.
Sets how "fast" the water looks.
Might need to be decreased to maintain stability if more aggressive values for speed are used.
Min Wave Vel
Sleep threshold for the simulation.
Sets how deep the moving layer of water is (in WaveSimCell units). Larger values make waves more 'dramatic'.
Sets a hard limit on wave height (in WaveSimCell units).
Sets how strongly moving objects transfer velocity to the water.
Sim Area Growth
If changing water level is expected to make the area expand, the wave sim grid should take it into account from the beginning. This sets the projected growth in fractions of the original size. If wave sim is not used this has no effect.
