reloadMaterial method

Future<Material> reloadMaterial(LocalId id)

Rebuilds one material while retaining already loaded texture resources.

Editors use this after changing a material descriptor. Re-running preload would decode every texture in the document even though the changed material normally references the same textures.

Implementation

Future<Material> reloadMaterial(LocalId id) async {
  final resource = document.resource(id);
  if (resource is! MaterialResource) {
    throw FsceneFormatException('Resource $id is not a material');
  }
  for (final value in resource.properties.values) {
    if (value case ResourceRefValue(:final id)) {
      final textureResource = document.resource(id);
      if (textureResource is TextureResource && !_textures.containsKey(id)) {
        await _preloadTexture(textureResource);
      }
    }
  }
  _materials.remove(id);
  switch (resource.type) {
    case 'fmat':
      await _preloadFmat(resource);
    case 'physical':
      await _preloadPhysical(resource);
    default:
      _materials[id] = tagResourceOrigin(_buildMaterial(id), document, id);
  }
  return _materials[id]!;
}
