'''Updated Dynamic Lighting''' (aka. '''UDL''') is the new version of the Roll20 lightning system that is meant to replace [[Advanced Fog of War]] and [[Dynamic Lighting]], combining them into a single, unified system. It features a stronger framework for future feature enhancements, is more performant, and has been updated for more current computing technologies. The old system is referred to as '''[[Legacy Dynamic Lighting|Legacy Dynamic Lighting (LDL)]]'''.

==General==
  
−
In UDL, the old features of '''Advanced Fog of War''' have been renamed '''Explorer Mode''' to avoid confusion. Updated Dynamic Lighting uses WebGL, which is available in most computer systems and is supported by all the web browsers that Roll20 supports (Chrome and Firefox). The [[Legacy Dynamic Lighting]] has always used WebGL, so the change here is that Explorer Mode (previously Advanced Fog of War) now runs on the same system.

On '''January 14th, 2021, Roll20 announced {{blog|640321601818198016/updated-dynamic-lighting-10-is-live Update 1.0}}''', saying that ''"Updated Dynamic Lighting has been in the works for some time, and we see the 1.0 Update not as a finish line, but a checkpoint."''. Despite this, there exists still multiple known issues, such as performance issues, and visual glitches relating to Darkvision.

==Parallel Systems==
+
==Features==
−
Currently, UDL exist in parallel with the [[Legacy Dynamic Lighting|Legacy Dynamic Lighting(LDL)]].
+
Breakdown of the main features.
 +
===[[Explorer Mode]]===
 +
{{#evp:youtube|8qVpF0olnVs|Explorer Mode & {{Darkness}} |right|500}}
 +
'''[[Explorer Mode]]''' - reveal map as characters move around the map, and leave previously explored section greyed out.
  
−
While they continue development on Updated Dynamic Lighting and support for licensed products, both the Legacy system and the Updated will exist in parallel. However, when you switch from one to another, the revealed areas are not transferred over. So, for example, if you and your crew have been crawling through a dungeon with [[Advanced Fog of War]] on, and you decide to switch to the new Dynamic Lighting with '''Explorer Mode''', your players won't see anything they had previously explored. Players can fix that by moving their tokens around to re-reveal the area.
+
With the {{Darkness}} you can create patches of explorable or permanent darkness, and it is also used for resetting Explorer Mode.
  
−
Similarly, if you switch to '''Explorer Mode''' and then decide to hop back over to the Legacy system, anything you had revealed in the UDL system will be reset/hidden when changing to LDL. If you then switch back to the UDL, the revealed areas that you had revealed when you last used UDL(might?) still be there.
+
In [[LDL]], the equivalent to Explorer Mode is [[AFoW]].
  
−
The [[Layers|Dynamic Lighting- layer]], where you can add barriers that block light and movement, continues to function for both systems, and you do not need to change anything on that layer.
+
You can also use Eclipses and freehand drawings for DL lines.
  
−
The [[Convert Lighting Tool]] making it possible to convert existing games to UDL automatically. '''This process can't be reversed easily''', so if problems occur and you want to change everything back to LDL, you need to manually update all tokens & pages yourself. It's recommended to create a copy of your campaign, and perform the Conversion on the Copy, and keeping the original game as it is.
+
If you turn on Daylight, you can adjust the brightness of the default light on the map.

====Dark Vision====
 +
In April 2021, {{hc|articles/360044771413-Updated-Dynamic-Lighting-Light-Vision-Examples#Alternate-Senses Dark Vision}} & Alternate Senses where released, making it possible to use D&D5E-accurate dark vision, if you turn on "Nocturnal Vision". Total darkness will by default be shown in grayscale, but you can change the tint to have a color. E.g. Night Vision technology could give you a green tint, while magic-based darkvision might make sense to have a purple tint.

===[[Darkness Tool]]===
−
Breakdown of the main features.
+
The {{Darkness}} can be used for manage what players can or can't see, reset explored map back to darkness, or draw Permanent Darkness that even blocks normal vision.
−
===Explorer Mode===
+
−
'''Explorer Mode''' - reveal map as characters move around the map, and leave previously explored section greyed out.
+
  
−
With the Darkness Tool you can create patches of darkness that can be explorable, and it can also reset areas that have already been explored.
+
It also incorporates features similar to the free [[Fog of War]]-tool, and replaces it's position on the [[Toolbar]] when UDL is active on a page. ({{fow}} isn't compatible with UDL).
  
−
In [[LDL]], the equivalent to Explorer Mode is [[AFoW]].
+
===Colored Lighting===
 +
Lights can have colors.

It also incorporates features similar to the free [[Fog of War]]-tool, and replaces it's position on the [[Toolbar]] when [[UDL is active on a page. (FoW isn't compatible with UDL).
+
You can quickly place lights, windows and doors on your map, with the '''Place Tool''' which can be found on the [[toolbar]].

+
−
* '''LAG''': We’ve heard you: Lag is the number 1 reason users aren’t converting to UDL. Since UDL started, we’ve put out a number of patches to improve performance; we are actively improving response times with each update. We’re currently testing a solution that will significantly improve network performance that we will be rolling out in the next couple of weeks.

===Parallel Systems===

{{notebox| As of Oct. 2021, UDL have several more features than LDL}}

This page is about a Roll20 feature exclusive to Plus & Pro-subscribers, or to players in a Game created by a Plus/Pro-subscriber. If you'd like to use this feature, consider upgrading your account.

(Updated ) Dynamic Lighting (aka. UDL) is the new version of the Roll20 lightning system, which is replacing the older Legacy Dynamic Lighting(LDL). It features a stronger framework for future feature enhancements, is more performant, and has been updated for more current computing technologies.

Feature Breakdown

[edit] General

[edit] Official Documentation

UDL was created after Roll20 had moved their Official documentation to the Help Center, so the Community Wiki doesn't have duplicates of these articles, so these features have better pages there:

[edit] Features

Breakdown of the main features.

[edit] Explorer Mode

Explorer Mode & Udl-hide-icon.jpg Darkness Tool

Explorer Mode - reveal map as characters move around the map, and leave previously explored section greyed out.

With the Udl-hide-icon.jpg Darkness Tool you can create patches of explorable or permanent darkness, and it is also used for resetting Explorer Mode.

In LDL, the equivalent to Explorer Mode is AFoW.

You can also use Eclipses and freehand drawings for DL lines.

If you turn on Daylight, you can adjust the brightness of the default light on the map.

Nocturnal Vision

[edit] Dark Vision

In April 2021, Dark Vision & Alternate Senses where released, making it possible to use D&D5E-accurate dark vision, if you turn on "Nocturnal Vision". Total darkness will by default be shown in grayscale, but you can change the tint to have a color. E.g. Night Vision technology could give you a green tint, while magic-based darkvision might make sense to have a purple tint.

[edit] Darkness Tool

The Udl-hide-icon.jpg Darkness Tool can be used for manage what players can or can't see, reset explored map back to darkness, or draw Permanent Darkness that even blocks normal vision.

It also incorporates features similar to the free Fog of War-tool, and replaces it's position on the Toolbar when UDL is active on a page. (C Fog of War isn't compatible with UDL).

[edit] Colored Lighting

Lights can have colors.

There is usually some delay between new UDL features getting introduced, and API scripting getting access to new object keys & functions to interact with them.

TokenMod(by The Aaron is a popular API that's been quickly updated when new UDL features have become API-accessible,

[edit] Comparison to Legacy DL

Roll20 have announced that LDL will be retired eventually More info:

In UDL, the old features of Advanced Fog of War have been renamed Explorer Mode to avoid confusion. Updated Dynamic Lighting uses WebGL, which is available in most computer systems and is supported by all the web browsers that Roll20 supports (Chrome and Firefox). The Legacy Dynamic Lighting has always used WebGL, so the change here is that Explorer Mode (previously Advanced Fog of War) now runs on the same system.

On January 14th, 2021, Roll20 announced Update 1.0(Blog, Archived), saying that "Updated Dynamic Lighting has been in the works for some time, and we see the 1.0 Update not as a finish line, but a checkpoint.". Despite this, there exists still multiple known issues, such as performance issues, and visual glitches relating to Darkvision.

[edit] Parallel Systems

As of Oct. 2021, UDL have several more features than LDL

Currently, UDL exist in parallel with the Legacy Dynamic Lighting(LDL), so you can use either one in your game, but LDL will eventually be discontinued.

While they continue development on Updated Dynamic Lighting and support for licensed products, both the Legacy system and the Updated will exist in parallel. However, when you switch from one to another, the revealed areas are not transferred over. So, for example, if you and your crew have been crawling through a dungeon with Advanced Fog of War on, and you decide to switch to the new Dynamic Lighting with Explorer Mode, your players won't see anything they had previously explored. Players can fix that by moving their tokens around to re-reveal the area.

Similarly, if you switch to Explorer Mode and then decide to hop back over to the Legacy system, anything you had revealed in the UDL system will be reset/hidden when changing to LDL. If you then switch back to the UDL, the revealed areas that you had revealed when you last used UDL(might?) still be there.

The Dynamic Lighting- layer, where you can add barriers that block light and movement, continues to function for both systems, and you do not need to change anything on that layer.

The Convert Lighting Tool making it possible to convert existing games to UDL automatically. This process can't be reversed easily, so if problems occur and you want to change everything back to LDL, you need to manually update all tokens & pages yourself. It's recommended to create a copy of your campaign, and perform the Conversion on the Copy, and keeping the original game as it is.

This is about a Roll20 feature exclusive to Pro-subscribers (and often to players in a Game created by a Pro-subscriber). If you'd like to use this feature, consider upgrading your account.

Roll20 Mod
Mod Suggestions

Mods by Category

Debug

Other

APIs have access to most UDL features, and some APIs such as TokenMod have updated to support UDL as best as it can.

There are some API, such as UDLWindows(Forum), which only works with Updated, and not Legacy.


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
