how to highlight or locate the gltf/glb model.Node

I'd like to see how to highlight or locate the gltf/glb model.Node.
I met with the trouble about it.When I get the node objects by the way of "getNode()",at the same time I want to locate or highlight it to show where it is in the whole models.However I couldn't found any properties like color or x,y,z(lon lat height) just matrix.Therefore I hope 2018 version can solve it to highlight gltf node.
node = model.getNode(id);
function createModel(id, url, height, lon, lat) {
var scene = viewer.scene;
var modelMatrix = Cesium.Transforms.eastNorthUpToFixedFrame(Cesium.Cartesian3.fromDegrees(lon, lat, height));
var model = scene.primitives.add(Cesium.Model.fromGltf({
id: id,
name: id,
color: Cesium.Color.fromAlpha(Cesium.Color.WHITE, parseFloat(1)),//viewModel.color viewModel.alpha
url: url,
modelMatrix: modelMatrix,
allowPicking: true
return model;

By the way,I used the version of Cesium 1.41.Thanks a lot.

At the moment it’s not possible to set the color of an individual node in a model.

I’m not sure what your use case is and how much control you have over your content pipeline, but this is possible with 3D Tiles.
