From Roll20 Wiki

Jump to: navigation, search

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


(Updated) Dynamic Lighting

Updated Dynamic Lighting(UDL) is the newer DL system Roll20 have been working on to develop as a replacement for LDL, and it was first made available in May 2020, and as of March 2021, still have some unresolved issues.

  • Explorer Mode is UDL's equivalent to AFoW
  • Udl-hide-icon.jpg 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
  • 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.

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.

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.


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

Check API:Script_Index#Dynamic_Lighting for list of some API that focuses on DL.

A number of API automatically detect which DL is used, and acts accordingly.
