How to publish an experience with Image Target

This tutorial will guide you through the steps to publish an Image Target in your experience and anchor 3D assets to it.

Step 1: Login and Create a New Image Target

1. Log in to your account.

2. In the top left corner, click the Image Targets button.

Step 2: Upload the Image Target

1. Click the Add Image button located on the top right.

2. Upload the image you want to use as a target, set a name, and define the asset's width in cm (the size must match the asset's real-life dimensions exactly).

3. Click Confirm to see how well the marker performs."

Marker quality is evaluated using the following criteria:

• Number of keypoints: Measures the number of distinctive features detected in the image. A higher number generally improves tracking stability.

• Contrast score: Assesses the difference between light and dark areas in the image. Higher contrast improves feature detection and recognition.

• Distribution score: Evaluates how evenly the key features are spread across the image. A well-distributed pattern enhances robustness.

• Angle variance: Analyzes the range of orientations of the detected features. A good variance ensures reliable recognition from different perspectives.

• Coverage score: Checks how well the detected features cover the entire image. Better coverage improves accuracy and tracking consistency.

Step 3: Create a New Project

1. In the top left corner, click the New Project button.

Step 4: Add an Image Target

1. Once the editor is open, navigate to the Asset section on the left side.

2. In the Asset Library, use the Image targets tab to filter and select the one you uploaded earlier.

Step 5: Link an asset to your Image Target

1. Now, choose any 3D asset you want to link to your Image Target. In this example, we will use an asset from OVER's Seasons collection.

Once the asset is imported into the scene, click the Group icon next to its reference in the Hierarchy. In the Select Group popup, choose the Image Target as the group. You will then see that the asset has become a child of the Image Target.

Step 6: Set Up Project Settings

1. Navigate to the Project section to configure the details of your experience.

2. Set a thumbnail or video preview for your project.

3. Select the layer where you want to publish your experience: AR Layer or Virtual Layer.

   • If publishing in AR Layer, make sure to enable the Display OVRMap option if you want remote users to experience the correct environment.

Step 6: Publish the Experience

1. Once all configurations are set, click Publish in the top right corner of the editor.

2. In the review popup, verify all settings and click Continue if everything looks correct.

3. Ensure that the occlusion settings are also properly configured if applicable, then click Publish.

Step 8: View the experience using the OVER app.

You can now visit the experience from the OVER app. Point your camera at the Image Target to see the 3D asset appear.
