Extensions on change trigger

Hello team Shapespark.

Does Shapespark support functions for changing options within extensions (with “type”: “MaterialPicker”) ?

I have a trigger with “name”: “1” and 3 Pick,
In there:
“toReplace”: “Flooring-light”,
“toPick”: [ “Flooring-Med”, “Flooring-Dark”],

==> I want to use the event to change it without having to click on the trigger.

There are no such functions.

Do you need to use the Material Picker extension? If not, you could change materials in the scene with JavaScript using the viewer API, see: API change material for another - #2 by jan

Thank you.

var dark = viewer.findMaterial('Flooring-Dark');
var light = viewer.findMeshesWithMaterial('Flooring-light');
var med = viewer.findMeshesWithMaterial('Flooring-Med');

for (var i = 0; i < light.length; ++i) {
  viewer.setMaterialForMesh(dark, light[i]);

for (var i = 0; i < med.length; ++i) {
  viewer.setMaterialForMesh(dark, med[i]);
