public enum TerrainLayerBlendHow a paint layer's texels combine with the layers under it.
Remarks
⚠ A different axis from TerrainBlend, and the design calls both of them "blend mode". TerrainBlend is a storage question — whether the layer takes part in the sum-to-one budget — and this is a shading one: given the weight the storage produced, how does the material combine this layer's albedo with the rest. A layer can be weight-blended in storage and height-blended in shading, and the common case is exactly that.
The three are [docs/plan/31 § D6]'s, and they are Unity's names because they are the ones an artist already knows.
Fields and properties (3)
WeightThe weight is the mix. Linear, and what a ground layer wants.
HeightThe layer's own height map biases the mix, so gravel shows through mud in its cracks.
AlphaThe layer's alpha channel gates it, so a decal-like layer can have holes.
