To start with the spark AR tutorial, first of all, you need to download Spark AR studio on a Laptop or desktop. To download it visit to spark AR official website or you can click here. Next, click on download. Wait for few minutes until it gets downloaded.

Go to the app store and download Spark AR player on your smartphone. Spark AR player is used to preview the filter that you created. Spark AR studio is used to create the filter. Let us move to the next step in the Spark AR tutorial.

·         Quick insight into the spark AR studio:

Spark AR studio by Facebook is used for creating filters for Instagram as well as Facebook.  It is equipped with immense features to help you be an excellent creator. It has room for beginners as well as advanced players. With the help of Spark AR studio, you can either add a computer-generated image to your surrounding or take yourself to any corner of the world. AR library has hundreds of audio and sounds, effects, patches, and more. You can use it directly from there or import your own asset from your desktop into the AR library. AR library scripts are issued under MIT License.

·         Explore AR library:

If you are a beginner, we recommend you in our Spark AR tutorial to explore all the assets available in the AR library. To open the AR library, click on Spark AR studio on your desktop. Here, sign up with your Facebook account to get started. Then click on ‘New project’. On the screen that opens up click on the file present in the top right corner.  Then click on search AR library.

In the AR library, there are thousands of free assets such as 3D objects, patch assets, music and sound, blocks, textures, and script packages. These assets are created by Spark AR creator and Sketchfab. Click on any of these, scroll and select what pleases you. Then click on import free > done.

NOTE: You can change the person in the viewport to yourself or some other options by clicking the video icon placed on the extreme left of your scene panel.

·         Explore the view board / Viewport:

Once you select the project you will be directed to the next screen, where on the left-hand side scene panel is present. Here, in this Spark AR tutorial, we will go for face decoration and add glasses. You can opt for whatever pleases you.

Click on a new project then click on Face Tracker.  There are three options available Plane tracking, target tracking, and face tracking. If you have selected the project that needs plane tracking such as adding snow then you should select Plane tracking. I have selected here face tracking because glasses are added to the face.  Glasses are here a 3D object so it gives a real-like feel.

You can download the sample object or create your own using any photoshop app. Now, go to the asset section and click on add from the computer. Select the sample that you just downloaded or that you have created. If your project is different go to add from the AR library and from there select the asset that you want.

Now, drag the asset you just imported to faceTracker0. You can see the shape of glass tracking the face on your screen which is also called the viewport.

·         Create the material:

Now we need to do changes here by creating and adding materials. To create a material you need to add the face mesh. Face mesh is like the child of the face tracker. To add the face mesh right click on the object that you selected -here we have selected Glasses_25D. on the scene panel then click on add then select the Face Mesh that you like. Now you can see the Face Mesh in the viewport as well as in the simulator.

Now, click on Face Mesh, the screen that appears on the right side is called inspector. Here click on the +sign placed next to material and select create new material. Soon we will see a new material added to the face in Viewport and simulator. Next, in the asset plane rename the material to glasses_mat. We rename it to keep the work organized.

·         Add texture to the material:

We can add different textures to the material so that users can switch between glasses designs. Click on glasses-mat and on the right side near texture add the designs that you have downloaded in the sample. Now, change texture from a single texture to sequence texture. Then select all designs that you have created or downloaded.

·         Animation texture

Click on add asset in the asset panel. Here, select the animation sequence and in the asset panel, you will see it with the name animationsequence0. Now go to glasses_mat in the asset panel. In the inspector click on the dropdown next to texture placed below diffuse. Then select animationsequence0. Now that we have our design on the screen we will move to the next step.

·         Create an occluder:

We create an occlude so that when someone turns the head the arm of glass can hide. To create an occlude click on Face Tracker > Add > Face Mesh. The steps are similar to the previous one. Now drag the Face Mesh to the top of the scene panel. Click on it and then in the inspector uncheck the eye and mouth box.  Create material and rename it to Occulder_mat. Now click on occluder_mat and change the shader to flat. Reduce opacity to 1% and check the double-sided box.

·         Switch glass frames and color:

You can skip this step if you do not want to switch between glasses or color. We will use patches to switch between color and frame. To switch frame click on animationsequenceo in asset Panel and in the inspector click the arrow placed next to the current frame. A patch editor will display. Now drag glasses_25D to patch editor. As soon as you will drop to patch editor it will change to purple color. Here right-click anywhere in the patch editor and in the display box search ‘object tap’ patch and ‘counter patch’. Next, connect the port or arrow of 4 patches as displayed below.
