Why are we not seeing more AR apps made in Unity?

Hey Guys,

Wanted to know from all the developers on why we are not seeing great markerless AR apps and games made with Unity? Is lack of a really powerful SDK the main reason? Or are there others?

I wanted to get a sense of what the community felt.


PS - Sorry for posting a question on AR in the VR part of the forums. But there wasn't a separate AR section.

Cheers!
