SurfaceLayerLook

One layer's own look, applied to what it reads before the layers are blended. Every field is the identity where it is absent, so a material names only what differs.

Explained in Hello world.

Properties

Name	Type	Description
`tint`readonlyoptional	`Vec3`	Multiplies the layer's colour, linear. Above 1 brightens it. Absent: `[1, 1, 1]`.
`roughness`readonlyoptional	`readonly [number, number]`	The roughness the ORM's green channel is spread over, from its 0 to its 1. Absent: `[0, 1]`.
`metalness`readonlyoptional	`readonly [number, number]`	The metalness the ORM's blue channel is spread over, the same way. Absent: `[0, 1]`.
`normalStrength`readonlyoptional	`number`	How far the layer's normal map bends the surface: its tangent-space x and y times this, before the layers' normals are blended. 0 is flat, 1 the map as it is. Absent: 1.
`specular`readonlyoptional	`number`	The layer's specular, in the units a mesh's vertices carry theirs: how strong a highlight is, and under `physicalSpecular` the reflectance head-on, `0.08 × specular`. Blended across the layers as their colours are. Absent: the surface's own, as its vertices give it.
