I have been having a lot of problems with multiple tracking in AR. I spent several days of my break trying to solve the code.
I did manage in the end to create the multiple image tracking. However, I was not able to mix the multiple tracking with the sound.
I searched for several days and made about 27 builds but had no luck integrating the sound.
I found one possible solution, which was an integration with Vuforia. However, the free versiion had a watermark and I wanted to be able to create something native to Unity.
Since the sound was the core of my project, I decided to reduce it to one target image and one animation.
Once the image is scanned, the band member will appear and its music will appear as well.
I absolutely loved the idea of this project, which is why I want to propose it as something scaleable in the future.
I am planning on continuing the exploration of the capabilities of Unity in AR and hopefully the fully customizable AR band will be possible in the future 🙂
