Function: findImageNode()

findImageNode(materialX, rootChild, maxNodes): any

Breadth-first search, starting at whatever node rootChild (an input wrapper, e.g. the surface shader's base_color input) connects to, for the nearest <image>/<tiledimage> node - the only node categories that actually consume a texcoord the way this module cares about. Bounded by maxNodes since a MaterialX graph can be arbitrarily large/cyclic-looking through interface references; this only needs to answer "is there an image lookup somewhere feeding albedo, and if so which one", not enumerate the whole graph.

Parameters

materialX

any

rootChild

any

maxNodes

number

Returns

any
