You will need to switch everything to UDL: map settings, token vision settings, and light sources. There is also an intermittent bug where tokens with vision have to be moved once before those settings 'take effect'. But yes I agree with you that initially making the change from a current LDL map to UDL is tough for just those reasons. Starting a map with UDL is quite a bit easier, and UDL is a better implementation now than LDL. (I was a UDL holdout for a long time.) Here's my standard troubleshooting checklist for vision: Make sure you are using Chrome or Firefox. Make sure you are set to only use either Updated Dynamic Lighting or Legacy Dynamic Lighting, not both. Token must have vision enabled. Token must be 'controlled' by the player who is checking vision. You should use a ' dummy account ' in order to see changes live/instantaneously when you make them as GM. There are other benefits as well (streaming, testing macros and other tricks, resetting the game URL). There needs to be a light source. Tokens always emit light from the center of the token -- in LDL it comes from a small point in the center of the image, and in UDL it comes from a circle that is some small percentage of the image size -- so if you set the map image as a light source, you'll get some funky behavior. Token and light source need to be on the correct layers. Do not use .webm animated tokens. They are currently bugged and often will not work correctly and prevent visibility. If a player cannot see, move their token. There is a bug with UDL that prevents player vision from 'activating' until after one of their tokens is moved on a page. Make sure you don't have a Fog of War/Permanent Darkness layer on. Make sure you don't have Advanced Fog of War/Explorable Darkness blocking vision. Explorable Darkness and Advanced Fog of War are saved for each player . Page 'Cell Width' settings can have an affect on a token's vision, especially if the 'light multiplier' is set to something other than 100%. Switch the Cell Width to '1' and see what happens. Check random other page settings, such as 'Restrict Movement' Make sure your view is centered on a token that has vision enabled and a light source Make sure you/your players are on the correct page. Double check that they have not been split from the Party ribbon. Clear your browser cache. Clear the game chat archive.
