Is there any property to show outline(border) color on 3dtileset to differentiate each tile feature?. In the above image, there are many tile features exist. How can i differentiate?
There’s a couple different things you can do to highlight the different features. You can create outlines as in the example here (they show up when you hover over a building):

This uses post processing. Another way is using the styling language, in this example, they’re colored different depending on the height, but you can use any feature property in the tileset instead:

Let me know if this helps!
