Didn’t try it but I don’t see why it wouldn’t work. Instead of a SetValueAction, try use ‘ExecuteCodeAction’.

As @mawa said, ExecuteCodeAction will work but note that a single action can be registered for the OnIntersectionEnterTrigger / OnIntersectionExitTrigger triggers (as per the doc): if you register several actions for those events, only the first one will be executed.

Here is the example - https://playground.babylonjs.com/#J19GYK#466
It does the same thing with donut scaling, but also changes its material.


    donut.actionManager.registerAction(new BABYLON.ExecuteCodeAction(
        { trigger: BABYLON.ActionManager.OnIntersectionEnterTrigger, parameter: sphere },
        function () {
            donut.scaling = new BABYLON.Vector3(1.2, 1.2, 1.2);
            donut.material = greenMat
        }
    ));

    donut.actionManager.registerAction(new BABYLON.ExecuteCodeAction(
        { trigger: BABYLON.ActionManager.OnIntersectionExitTrigger, parameter: sphere },
        function () {
            donut.scaling = new BABYLON.Vector3(1, 1, 1);
            donut.material = blueMat
        }
    ));
