This feature is the Advanced Version of the Fog of War tool that is available to Plus and Pro Roll20 Subscribers. If you want to know more about the Standard Fog of War Feature, please go here.

The Advanced Fog of War feature clears fog away dynamically as a token moves across the Page and the Fog of each player's view will only be revealed by the tokens they have control over. Similar to how a battle map is revealed in a real-time strategy computer game, the area that the token moves out of, remains revealed to the players in desaturated colors until they return. Monster and NPC tokens that are not in the player's token's current area of play will not be visible, even if they are present in the previously revealed areas of the Page. This allows you to reveal an ever expanding maze of a dungeon to the party, room by room, while they explore without having to manually clear the fog away for them. This feature can also be used in combination with Dynamic Lighting to block line of sight along dungeon walls and other obstructions.

How it Works


Enabling Advanced Fog of War

To enable Advanced Fog of War, go to the Page Settings dialog of the page you wish to enable it on. Beneath the Standard Fog of War checkbox is a section for the Advanced Fog of War features. There are four settings that can be adjusted here:

  1. Advanced Fog of War Enable Checkbox: The Enabled checkbox will turn Advanced Fog of War on for that page when checked.
  2. The Size Input Field:' The Size number input field is only visible if the Page Settings has the Grid currently disabled. Advanced Fog of War requires a grid to calculate which areas of the Page are hidden or revealed. With the Grid turned off on a Page, this setting will allow you to dictate how large the square cells are that are revealed when the token is moved across the Page. At default, this field is set to 1 unit and utilizes the Scale you're using at the top of the Page Settings dialog box.
  3. Show Grid Checkbox: The Show Grid checkbox is a feature tied to Dynamic Lighting. When Dynamic Lighting is enabled on the page, the grid lines will be hidden over areas not within a token's line of sight even if those area of the Page has been revealed from the Fog. Enabling Show Grid checkbox will make the grid visible over all revealed areas of the Page. The grid used for the Advanced Fog of War in this scenario is purely for calculating the Fog of War, it will not generate a visible grid on your gridless Page.
  4. 'Dim Light Reveals Checkbox: By default, if a Token has a light setting established on the token's Advanced Token Settings, it will reveal an area that is only in "bright" light. It will ignore the larger radius that is cast in "Dim" light if available on the Token Settings. The Dim Light Reveals checkbox, once checked, forces the boundary of the reveal to include both bright and dim light cast by the Token.

{{mbox | text = Note: If you have a vision distance set in the Advanced Fog of War section of a token's Advanced Token Settings, the Emits Light settings for that token are completely ignored regardless if you have #Dim Light Reveals enabled or not on the Page Settings.
