you can just make the tiles inert until picked up baka theres an unreleased mahjong map that has it setup that way 

This one actually works right now but it's set to max players 1 and isnt public

you can just make it so on pickup the tiles then become physical/able to interact.

i think the way they set it up here was the tiles are just literally technically floating

[spoiler]They also have a little glass thing for when people draw it makes the tiles all look blank so you dont accidentally catch a glimpse[/spoiler]

Also don't forget the camera to watch discards
