Type Alias: DisplaceChannel

DisplaceChannel = "rg" | "luminance" | "alpha"

Defined in: attributes/shape/effects/implementations/displace.ts:15

Which part of the map drives the displacement.

"rg" — red moves pixels horizontally, green vertically. The convention every normal/flow map is authored to, and the only one that can push in two directions independently.
"luminance" — one value drives both axes. What a grayscale bump map means: the brighter the pixel, the further it is pushed along amount.
"alpha" — the map's alpha, for displacing from a cut-out shape.
