I'm playing a tabletop RPG campaing with lots of 3d maps and models and the players hands are always moving around, picking up models and stuff but since the scale of the maps are very small, the hands are huge and kinda annoying especially considering that I stream the whole thing on twitch. (how it looks: https://imgur.com/a/kjxRP09 )

I can't change the scale of the maps without breaking lots of stuff, I tried messing with fog of war settings but it doesn't solve the problem.

Is there a way to hide them?
