Multiple AR tracker not working.

Hello everyone, I am an architecture student and I am using Unity for building an augmented reality scene. I'd like to use 3d trackers and 2D trackers in the same scene. I tried many times so far and I noticed two things.

• Unity is able to read no more than 2 3d trackers in the same scene together.

• Unity is not able to track multiple 2d trackers at the same moment.

I wonder if there is any way to build a scene where there are -two 3D trackers -six 2D trackers

And having a stable response. Sometimes I follow tutorials but ends always troubleshooting for the next week after the tutorial.

Thanks for every information you can provide me. Also, I am from Los Angeles. I would be down to meet some unity expert and have a chat.

Thanks,

Alessio

ps. I am not a coder. But I am open to learning everything that makes this thing to work.
