tracking pupils + skin shades

Hi Daniel!

1. You can swap the materials using this script 

// -----JS CODE-----
// @input Asset.Material[] materials

var nextMaterialIndex = 0;

// Define what happens when you tap.
function changeColor () {
// Get the item's mesh visual
var meshVisual = script.getSceneObject().getFirstComponent("Component.MeshVisual");

// Clear previous material, and add the new material
meshVisual.clearMaterials();
meshVisual.addMaterial(script.materials[nextMaterialIndex]);

// Increment index for the next material
nextMaterialIndex = (nextMaterialIndex + 1) % script.materials.length;
}

// Bind the function to the touch event.
var touchEvent = script.createEvent("TapEvent");
touchEvent.bind(changeColor);

// Start if off
changeColor();

Add this script to the object that you want to change:

Then you can add value in the materials field and the script will swap through them when you tap the screen.

2. It is not possible to track the pupil at this time.

3. You can select your camera object. You can right click the Input field in the Inspector panel to remove Device Camera Texture from its input. The camera will then use the Clear Color field as the background for your 3D object:

Can't wait to see what you come up with!

Cheers,
