doesn't work well because isn't the same as instagram.com/ar/557360958567475 that have a border on the gate, so one can enter inside the cube where there are other objects that one can approach, how did you do that? can you share that project? please Raghav Agarwal
jaime yes I know its not the same, but it is the base for the whole project.
The door is an asset from the SparkAR asset library which you can download and add in your project.
Also if you move towards the door, you can enter inside it. I have added the touch and hold gesture for the user to enter inside the portal easily.
I will share the project with these features in few days :)
