Local VTT isolating sight for each token

Hello I just bought my first roll20 module and subscribed at highest level. We use a tv flat on its back as our map and have 1 pc running controlling all the player tokens. I'm trying to figure out if there is a way to isolate each token's line of sight when that player's turn is up. As it is now all players can always see everything all tokens can see. As a DM on my separate laptop I can use control+L to see what a single token sees but the player's can't seem to use that command. It would be hand to be able to quickly turn on this isolation to determine exactly what an individual token can see and have the player act on that information just like they would if each player had their own screen and account logged in. Thanks

Yup! &nbsp;I build the Observer script for that exact situation. Here’s a page that should help:&nbsp; <a href="https://wiki.roll20.net/Using_Roll20_while_Playing_In-Person" rel="nofollow">https://wiki.roll20.net/Using_Roll20_while_Playing_In-Person</a>

Thank you, is there a way to make it so the tokens representing characters without dark vision can't see light emitted by tokens with darkvision? I'm told the normal way to represent dark vision is just have that token emit light that only that player can see. However, since all tokens are controlled by the same account all tokens are seeing this light and characters without dark vision see too much.
