How to slowly enable a texture

  • The Marker template comes with a script called MeshFadeController.


    Is there anyone familiar with this template that can tell me if i can alter this script so I can fade into the FaceMask instead of the mesh its made for?

    Description of MeshFadeController is below


    // MeshFadeController.js

    // Version: 0.0.1

    // Event: Lens Initialized

    // Description: Fade in and out the 3D meshes using fizzle.

    // @input bool fadeEffect = false

    // @input string fadeType = "startFadeIn" {"widget":"combobox", "values":[{"label":"Fade In", "value":"startFadeIn"}, {"label":"Fade Out", "value":"startFadeOut"}], "showIf": "fadeEffect"}

    // @input float fadingDuration = 1.0 {"widget":"slider", "min":0.1, "max":5.0, "step":0.01 , "showIf": "fadeEffect"}

    // @input Asset.Material[] fadeMaterials {"showIf": "fadeEffect"}

  • Hi Loupis1!

    You can use the TweenManager helper script to help with this. 

    First add the Tween Manager

    Then select your Face Mask in the Objects panel. In the Inspector panel, at the bottom  choose Add Component and add the Tween -> TweenTypes -> Tween Alpha script in the file selection window. 

    Now you can control how your mask fades in with the TweenAlpha script!

  • Thanks Jonathan! 

    Follow up question. TweenAlpha is allowing me to fade the FaceMask in but there's a problem. 

    I'm using the Full Screen template that allows me to switch through different face masks on tap. 

    When I add TweenAlpha to the facemask object it causes the face mask to fade in after i tap BUT the facemask is fully visible for a flash of a second before the fade begins.

    Can i fix that? Sorry if its confusing.

  • Hi, loupis1!


    There are several ways

    1. You can set your face mask alpha to 0 at the beginning

    2. Use a behavior script (set color alpha to zero):

    3. Or via code:

    //@input Component.FaceMaskVisual faceMask

    function setAlpha(value){

        var color = script.faceMask.mainMaterial.mainPass.baseColor;

        color.a = value;

        script.faceMask.mainMaterial.mainPass.baseColor = color;


    setAlpha(0); //call this when you need to reset
