[Technical issue ?] Light barrier on a token

HI all, Is there a way to add a light barrier (blocking sight then) to an object or token ? For example, a spellcater uses wall of fire. Characters shouldn't see through it. Is there a way to add a dynamic lighting barrier on the default token ? or do the gm has to go on the DL layer and add a line along the spell area of effect ? silly question but might make people think about it... :) Thanks in advance for at least think about it.

It would need to be added manually, though it could be automated with an API script.

Is there an existing script doing it ? something like pairing a token and a barrier as a default token ?

I'm not aware of a script that ties custom-shaped DL barriers to a token. I *do* have a simple script that creates a circular DL shape based on the dimensions of a token (used for the darkness spell or obscuring spheres like cloudkill). UDL Disclaimer: Note that if you decide you like the interior grid option and you use UDL, that part doesn't work currently. There is a bug in the UDL implementation that doesn't allow for complex paths. LDL is fine, and UDL if you only use the perimeter circle is fine. The following example shows the DLDarkness script in conjunction with the SpawnDefaultToken script for a 5e cloudkill. Click for animation:

Nothing that comes to mind. There are some similar things. I know there is a darkness script that causes DL lines to follow a token, butnothing that will do that off the shelf that I can think of.

David M beat me to the punch with a much better answer. Serves me right for answering on an hour-old tab without refreshing first.

haha, I do it all the time! :)
