Adding a Cube so that we can test the target

With the Image Target still selected, Right Click on the Image Target, Under 3D Object click Cube

Resize and Move the Cube so that it is on top of the Image Target’s preview. It should look something like this now

Select your Image Target, and Move your Image Target to the side a little bit. This will help later when we have more Image Target, so that it does not overlap each other. You will see later on when you have multiple Image Targets.

Press Play and show your image to the camera. It should work now and you will see your cube appears on top of your image.

Repeat this for all your image targets
