DrawGrouping

The fields a merged group carries, resolved from a material and its override.

interface DrawGrouping

import type { DrawGrouping } from '@driftengine/assets';

In depth

Named for what they are on a group rather than for what they are called on a material — ormMap is orm here — because these are the values the renderer is handed, and the group is what holds them between the loader and the draw.

Properties

Name	Type	Description
`albedo`readonly	`number`
`orm`readonly	`number`
`normal`readonly	`number`
`emissive`readonly	`number`
`opacity`readonly	`number`
`reflectivity`readonly	`number`
`roughnessScale`readonly	`number`
`metallicScale`readonly	`number`
`occlusionStrength`readonly	`number`
`cutout`readonly	`number`
`blend`readonly	`boolean`	Whether the texture's alpha is coverage, so the part is drawn blended whatever its opacity.
`doubleSided`readonly	`boolean`	Whether both faces are drawn and lit. A merge of a two-sided part and a one-sided one would cull one of them or unhide the back of the other, so it is part of the key.
`transmission`readonly	`number`	Glass. Zero transmission is not glass, and then frost is 0 and the tint white whatever the file or the override said, so a stray value on an opaque surface never splits a draw.
`frost`readonly	`number`
`tint`readonly	`readonly [number, number, number]`
