[SOLVED] How to use stencil buffer?

Seems that there is no tutorial for this topic on this site

And stencil buffer is mentioned in many different docs like Material, GraphicsDevice and Camera, which is confusing.

If possible can someone provide a demo where the model being applied with a special material always fails the stencil test? Huge appreciates!

There is an example in the github repo of using stencil parameters on materials. It’s not super clear, but hopefully enough to get you started?

<body>
    <!-- The canvas element -->
    <canvas id="application-canvas"></canvas>

    <!-- The script -->
    <script>
        var canvas = document.getElementById("application-canvas");
        canvas.focus();

        // Create the application and start the update loop
        var app = new pc.Application(canvas, {
            keyboard: new pc.Keyboard(window)
        });
