Roll20 currently have two Dynamic Lighting systems, which are not interchangeable.

[edit] Dynamic Lighting

Dynamic Lighting (UDL, formerly known as "Updated Dynamic Lighting") is the newer Dynamic Lighting system Roll20 have been working on to develop as a replacement for LD. It was first made available in May 2020, and as of Q1 2022, has more features & generally seen as better than LDL.

Explorer Mode is UDL's equivalent to Advanced Fog of War
- Dark Vision
Darkness Tool is a tool that can be used to manually reveal or hide visible areas while using UDL. Fog of War is the free version of this tool, which is compatible with LDL
Colored_Lighting
One-Way Barrier
Place Tool
Convert Lighting Tool - for one-way converting Lighting settings & tokens in a game from LDL to UDL. Recommended to be used on a copy of your campaign, as you can't change things back with a single click.

[edit] Legacy Dynamic Lighting

Legacy Dynamic Lighting(LDL) is the original system, previous referred to as just "Dynamic Lighting", and is what people talk about in any guides or videos made before April 2020. It's on its way to being removed.

Advanced Fog of War(AFoW) - A part of LDL

[edit] General Info

On both Tokens and the Page Toolbar, the setting for LDL and UDL are on separate pages, as not to confuse people.

Roll20 have announced that LDL will be retired when UDL is good enough..

Fog of War is not impacted by removal of LDL.¹ ² ³

[edit] API

Some API, such as TokenMod, support both LDL and UDL. There are still some UDL settings that API cant currently access.

A number of API automatically detect if Updated or Legacy DL is used, and acts accordingly.

Dynamic Lighting is a Plus/Pro feature that changes what parts of the map are visible to the players as they move their tokens around. The light-blocking walls are achieved by paths on the walls layer, and tokens are used as point light sources. Scripts which modify either the light emitted by tokens or the walls which block the light belong in this category.

Not all APIs, or all their features work on both Updated DL and Legacy DL, you have to check them closer to know that.

DLTool^(Forum) - A Dynamic Lighting Control Panel and Troubleshooter by keith
Door Knocker -- Script helps quickly open and close doors by controlling the dynamic lighting lines, as well as creating "windows"
DLEllipseDrawer -- Draw circles and ellipses on the dynamic lighting layer.
Dynamic Light Recorder -- Save dynamic lighting paths for map tiles and automatically regenerate later
LightCrumb (UDL version), by Aaron (not tested)
Move Lighting -- Move dynamic lighting polygon path objects between layers.
Walls -- Builds Dynamic Lighting walls with an exported .svg path file.
ShareVision -- Allows normal vision and darkvision to be shared.
ToggleDaylight^(Forum) -- turn daylight mode on, off, or toggle it for LDL or UDL on the current page.
Script:UniversalVTTImporter For importing Dynamic Lighting lines & light sources to Roll20 from map creation programs that can export to Universal VTT-file format.

Following Mods no longer work as well as previous, since real Doors and Windows where introduce:

UDLWindows^(Forum) -- API for creating "windows", i.e. DL lines that blocks movement, but doesn't block vision.
UDLPasswall^(Forum) - Walls that block sight, but not movement

APIs that only works with Legacy

LightCrumbTrails^(Forum) -- Produces lit, shared-vision breadcrumbs behind character tokens. This allows them to see where they've been on maps with dynamic lighting.
One-Way Dynamic Lighting^(Forum) -- Allows you to set up dynamic lighting walls that allow you to see through one side, but not the other.
Torch -- A simple script for giving lights to tokens and turning off and on dynamic lighting.
- UDL version in the works

-In addition to the Map &amp; Background Layer, the Object &amp; Token Layer and the GM Overlay Layer is the Dynamic Lighting Layer. This fourth layer’s purpose is for laying down lines and shapes that will serve as walls and/or obstacles that will block out light or line of sight.

-== How to Activate Dynamic Lighting ==
+<br>
-[[File:Pagesettingslighting.png|thumbnail|Dynamic Lighting & Fog of War checkboxes under Page Settings.]]
+[[Category:Dynamic Lighting]]
-Open up your [[Page Settings]] and check the checkbox to activate Dynamic Lighting for that page. The first option Enables the dynamic lighting and the other options add functionality to the dynamic lighting system. ''You can use [[Fog of War]] in combination with Dynamic Lighting, but one is not dependent on the other to function.''
-If you or your players suffer from sluggish dynamic lighting render results you might want to consider checking the option '''Only Update on Drop'''. What this option does when checked is that the tabletop only redraws the dynamic lighting ''after'' a token has been picked up and placed elsewhere on the map. This can lessen the render burden for users running on old computers or when a GM is working with a very large or complex map.
-== How to Add Light Obstructions ==
-[[File:DL_Walls.jpg|thumb|left|Using bright colors can help in setting up your light boundaries, the boundry lines are only visible on the dynamic lighting layer.]]
-While on the Dynamic Lighting Layer, you can use all of the drawing tools available to create lines and shapes to draw walls, columns, doors, etc (except the freehand tool). You can also utilize color to help differentiate different types of light obstructions (ex. lime green for stationary dungeon walls and bright red for doors).
-Use the drawing tools to draw outlines of all the walls and other pieces of the map that you want to block light. We suggest using the [[Drawing_Tools#Polygon.2FLine_Tool|Polygon Tool]] for best results. Due to the performance hit associated with using it, the [[Drawing Tools#Freehand and Shapes Tools|Freehand Tool]] is disabled while you are on the Dynamic Lighting layer.
-Remember that any drawings or tokens added to the dynamic lighting layer are invisible whenever the dynamic lighting layer is not selected. You can use this fact to put overhead or other 'invisible' lighting sources on a map by placing light emitting tokens onto the Dynamic Lighting layer.
-'''Note:''' Presently, circles drawn with the Circle Tool do not render light blocking correctly. Instead of using circles, create a rounded shape with the Polygon Tool.
-If you plan to block out a multi-room/complex map, it's recommended that you build the light blocking with smaller individual lines. This makes it easier to select and move around the shapes you add to the layer.
-<div style="clear: both; height: 10px;"></div>
-== Adding Light ==
-[[ File:Tokensettinglighting.png|thumbnail|right]]
-Now that you have your obstacles drawn out on the Dynamic Lighting Layer, you have to add light to your Page. Light is emitted via tokens. Create a token and place it on the map.
-Double click on the token and select the '''Advanced''' tab.  There you will find the option '''Emits Light'''. This option allows you to enter a light radius amount and gives you a checkbox for '''All Players See Light'''. When the checkbox is left unchecked, the only player(s) who can see that token’s light emission are those who have assigned permission to that token.
-By default, the light will start to "dim" about 5 feet (or units) before the selected maximum radius.  This effect can be modified by using the optional "Start of Dim" value in the "Advanced" tab.  To make the dimmed area larger, set the "start of dim" value to be much smaller than the radius (e.g., 20/5).  To make the edge of the light a "hard" transition, make the "start of dim" value larger than the light radius value (e.g., 20/30).
-It is possible to create dim light with no bright source. This is useful for creating effect where the light is coming from under a door or through curtains or shutters. Simply set the "Start of Dim" value to -5
-Hold down the alt key while moving the token to prevent it from snapping to the grid.

-== Line of Sight ==
-Line of Sight restricts players to only see lights that are within the appropriate field of vision for the tokens that they control.  This means that a light on the other side of a wall won’t be visible to a player until they’re in that room, even if it’s a light that’s visible to all players. The image below shows the difference between a dungeon without line of sight, and then with line of sight enabled:
-[[File:Lineofsight.gif]]
-To enable line of sight you will need the "Line of Sight" Checkbox on the Page Settings checked, as well as having one or more tokens that the player controls have "Has Sight" checked otherwise your players won't see anything but darkness.
-GMs can also highlight a token and press Ctrl+L (Cmd+L on Macs) to view the scene restricted to the line of sight of the selected token.
-In addition to the line of sight feature, you can now customize the “angle” of lights and the line of sight of tokens. So you can specify, for example, that a player should only have a 140-degree field of view instead of the default 360-degrees.  To do so, use the "Angle" setting on the Token Settings screen to change the angle of the light emitted or the angle of the line of sight for the token.
-The token's vision can be further customized using the multiplier feature. The multiplier affects how far the token can see from existing light sources. This is a good way to simulate a character who has the ability to see further than normal in low light situations or has an alternate form of vision that might allow them to navigate in the dark. For example, someone who can see twice as far in low light would have a multiplier of two.
-== Restrict Movement ==
-[[File:restrictplayermovement.gif|right]]
-The "Restrict Movement" checkbox enforces that player controlled tokens, that also have the "Has Sight" box checked, cannot cross over Dynamic Lighting Obstructions. This ensures that players don't move outside the intended map area and accidentally reveal parts of the map their tokens couldn't otherwise see. It can also be used without Dynamic Lighting checked as a way of restricting parts of the map from player token movement.
-== Global Illumination ==
-With "Global Illumination" checked along with "Enforce Line of Sight" the map is blanketed in light, with the only restriction to vision being Dynamic Lighting Obstructions. This options simulates daytime, outdoor, or brightly lit environments where the only limits to range of vision are physical obstacles.
