Let a player see through walls?

I have a player who is supposed to be able to see through walls within a certain range as a constant effect. Does anyone know of a way, through dynamic lighting settings or an API script, that would allow one player (but not the others) to see through the dynamic lighting walls?

Not automatically, but you can set up a workaround that will work with some coordination with the player. Set up an invisible token (<a href="https://app.roll20.net/forum/post/5600954/invisible-tokens" rel="nofollow">https://app.roll20.net/forum/post/5600954/invisible-tokens</a>) with a 0-foot aura so you can see it. Have the token emit light only it can see to about half the distance that the PC should be able to see through the wall. Assign the token as a default to an NPC character sheet controlled by the player. When the PC gets close to a wall they want to look through, drop the token on the other side of the wall.
