Exported Mesh - polygon selection / control

I ‘imported’ a mesh. Each polygon has a name ID.
I know how to control it using html with a button element:

var myBtn = document.createElement(‘button’); //button object

let myMesh = scene.getMeshByName(“my_mesh”); //declaring mesh by ID name

I am trying to have a onRollOver, onClick effect on the polygon itself so it is both targeted and reacts like changing color or popping up text, rather than using an html button.

Thanks! :slight_smile:

Maybe this thread can help regarding the highlighting effect on mouse hover?

A simpler one:
