TexturedNormalMapFeature

Remarks

What NormalMapFeature could not be for as long as a feature could not sample. That one carries a single NormalTS constant, which bends a whole surface one way and is a normal map in name only — useful for a decal or a test and nothing an artist authored.

Same seat as TexturedMetalRoughnessFeature and the same conditions: a name rather than a handle, a device with HasBindless, and a host that paired the name through MaterialRenderFeature.TextureIndices. Without the pairing the index stays zero and the surface is shaded by the table's fallback read as a normal, which is why the fallback being obviously not a surface matters twice over.

Composes beside a base surface rather than replacing one: it writes normalWS and touches nothing else, so a material is a textured base colour and a textured normal, which is the shape every other feature in the chain has.

Fields and properties (3)

• public string NormalMap

  What the material calls the tangent-space normal map it wants sampled.

• public float Strength

  How far the normal is bent, where 1 is as authored.

• public string ShaderName

  The Raven shader implementing this feature, from Raven/Library/Material.

Methods (2)

• public static string NormalIndexParameter(string path)

  What the shader calls the slot, under a composition path.

• public void Compile(MaterialCompilationContext context)

  Writes this feature's parameters, and fills any slots of its own.
