VolumetricFogAsset

Remarks

Paired with FogAsset exactly as GlobalDistanceField is paired with DistanceFieldAoAsset: this fills a volume and names it, and the fog node reads the name. A document with one and not the other is not broken — the composite falls back to the analytic falloff, and the dispatches nothing reads are culled by the graph.

Fields and properties (23)

• public string Name

  The node's name, for debug groups and for a human reading the file.

• public bool Enabled

  Whether the node runs.

• public string View

  The view whose camera the froxels are laid out in front of.

• public string Media

  The names the three volumes are published under.

• public string Scattered
• public string Output
• public string ShadowAtlas

  The cascade atlas the froxels are shadowed against.

• public bool Shadows

  Whether the froxels are shadowed against those cascades at all.

• public string ScenePass

  Whose published cascades and biases the shadow taps use.

• public int Width

  How many froxels across, down and deep.

• public int Height
• public int Slices
• public float Near

  Where the grid begins and ends, in metres of view depth.

• public float Far
• public float Density

  How much light a metre of the medium takes out of a ray.

• public Vector3 ScatteringAlbedo

  What fraction of that is scattered rather than absorbed, per channel.

• public bool HeightFalloff

  Whether density thins with altitude.

• public float FogHeight

  The altitude the authored density holds at, and how fast it thins above.

• public float HeightFalloffRate
• public Vector3 SunDirection

  Which way the light travels, and what it carries.

• public Vector3 SunColour
• public float PhaseG

  Henyey–Greenstein anisotropy.

• public Vector3 AmbientColour

  What arrives from the whole sky. ⚠ Without it a back-lit valley is black.
