Thank you Keith! It was the lack of tokens on this map that caused the problem, it appears. Thank you for helping me troubleshoot this. keithcurtis said: Phil C. said: I am having trouble with the Alien Chariot of the Gods adventure I purchased. The screen for the Cronus map displays fine for DM but is in total darkness for players. The Montero map and other screens don’t do this. The map remains dark even if I set the settings to daylight mode. Revealing darkness doesn’t seem to work either. Hi Phil! I cannot duplicate this. If I turn on DL and Daylight mode, place a token and give it sight, and give the player control permissions, It displays for both me and my Dummy Account player on that map. My best advice is to verify: Player and GM are both on the same map, with player flag (The Split the Party function has not been used) The Player controls the character the token represents. (not just "In Journal" permissions) The token has sight The token is on the token layer and the player can grab and move it. The map has DL and Global illumination active. Here is a more thorough checklist: Here's a "why can't my players see anything?" checklist. The important thing is to verify. Don't assume. This list is written with GMs in mind, but can help players work through issues with their GM. The token is on the VTT It is assigned to the character The player has control over the character The token is on the Token/Object layer It is not blocked off by DL lines from seeing the immediate surroundings Make sure the player is looking at their token's immediate area. Shift-Click and hold on the token to pull the player's view to that area. If Fog of War is being used, that the area the token is in has been cleared The player has not been Split from the Party (Check the Help Center if this is unfamiliar) If Dynamic Lighting of any kind is being used: The token has sight turned on The token has a light source, or Nightvision (UDL) or personal light (LDL) In UDL it may be necessary to move the token one square to get everything working, or in extreme cases, refresh the (user's) page. Can you see a rotating cube in this URL ? If not, the browser needs to be WebGL compatible (99%+ are). If you are a Pro User, the Dynamic Lighting Tool script has diagnostic functions that will check many of the points above and give a report on likely causes, along with quick fix buttons. Finally, here is a guide to best practices for Dynamic Lighting Performance .
