TerrainNodeAsset

Remarks

One node for the whole stack, deliberately. The surface, the grass scatter and the grass draw are one decision about where in the frame the ground goes — after the opaque pass, sharing its depth — and a document that could place the scatter without the draw would be offering an order nothing can want. What it draws is the world's TerrainComponent entities, not a terrain named here: which ground exists is the scene's, and the document only says where in the frame it lands.

The defaults are !StandardFrame's names, so the whole installation in a standard frame is three lines of extensions: — afterOpaque: [!Terrain {}] — and a hand-authored document names its own targets instead.

⚠ The nullable scalars are the quality waterfall's seam. Null means "whatever the factory was configured with", which is where a host folds its resolved quality tier; a written value is this document deciding, which out-votes the tier the way a !StandardFrame's own knobs do. See Vegetation.

Fields and properties (19)

• 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 Output

  The colour target the ground draws into — an existing one, loaded rather than cleared.

• public string Depth

  The depth target it tests and writes — the scene's own, so occlusion works both ways.

• public string View

  The view whose camera places, culls and streams the ground.

• public string Albedo

  The frame's split albedo plane. Its presence is what turns the split path on.

• public string Normals

  And its normal plane, on the same terms.

• public string ShadowAtlas

  The cascade atlas the frame renders, which the lit ground samples.

• public string ScenePass

  Which pass's names the frame's lighting is published under.

• public bool Grass

  Whether grass fields scatter and draw at all.

• public float? GrassDensityScale

  What fraction of each grass field to keep, 0…1, or null for the factory's tier.

• public float? GrassCullDistanceScale

  A multiplier over every grass type's authored cull distances, or null for the tier.

• public int? GrassResidentCells

  How many grass cells stay resident per field, or null for the tier.

• public int? GrassBladesPerCell

  How many blades one cell's run holds, or null for the tier.

• public float? TerrainNearRange

  How far level 0 reaches for a terrain whose component left it at zero, or null for the tier.

• public float? FoliageDensityScale

  What fraction of each foliage volume to draw, 0…1, or null for the factory's tier.

• public float? FoliageCullDistanceScale

  A multiplier over every foliage type's authored cull distances, or null for the tier.

• public int? FoliageCellBudget

  How many foliage cells one volume's streamer keeps uploaded, or null for the tier.

• public int? TerrainStreamingMegabytes

  Megabytes of staged tile chains a terrain's streamer may hold, or null for the tier.
