of static method

MaterialsVariantsComponent? of(
  1. Node root
)

Finds the first variants component for a loaded model.

The runtime importer attaches one component to the model's root; the .fscene realizer attaches one per document root (below the synthesized scene root). This searches root and then its subtree breadth-first, so callers work with either import path. A multi-root document can carry several components; use allOf to reach every one.

Implementation

static MaterialsVariantsComponent? of(Node root) {
  final all = allOf(root);
  return all.isEmpty ? null : all.first;
}
