Selecting Elements and Changing it's color of GLB

Hello Team,


I have a GLB model which I am adding it into the cesium ION and tiling it as a 3D tileset.
Here is cesium sandcastel link for the same.
GLB loading

What I want to do in here is select an element say window, door, wall and then change it’s color.
How can I acheive this ?

Any kind of help will be greatly appreciated.
Thank you !!


How do you define each element, ie a window or door?

There are a few different techniques depending on how the element is stored.

For reference, this is a common use case enabled by 3D Tiles 1.1 metadata support.
