Hi @heung_aile
In this case you can run onMaterialClicked(<MaterialName>, callback>
Then you won’t need to find material first
Your script could look like this:
var viewer = WALK.getViewer();
viewer.onMaterialClicked("Painting03", function() {
alert(1)
});
For reference, findMaterial function must be run after the scene is ready to display GitHub - shapespark/shapespark-viewer-api: JavaScript API for interacting with the Shapespark 3D scene.
