Adds attenuation vision to limited walls of Foundry VTT.
Foundry always shows the entire area delimited by limited walls. The added attenuation changes the visible area to only a portion near the token, so the other side is not revealed.
Configuration
In the wall configuration, enable the Has Limited Attenuation option and set a ratio in Limited Attenuation Ratio from 0.05 (hide 5% of the area) to 0.95 (hide 95% of the area).
Settings
You can set the Default Limited Attenuation Ratio (default is 0.5) to use when enabling Has Limited Attenuation in the wall configuration.
