Hi Tanner, I'd recommend reading the sections on Dynamic Lighting on the wiki, especially the system specific ones here (linked to the 5e section, assuming that is what you are playing): <a href="https://wiki.roll20.net/Dynamic_Lighting_Examples#Dungeons_and_Dragons_5th_Edition" rel="nofollow">https://wiki.roll20.net/Dynamic_Lighting_Examples#Dungeons_and_Dragons_5th_Edition</a> and the basic info on lighting here: <a href="https://wiki.roll20.net/Dynamic_Lighting" rel="nofollow">https://wiki.roll20.net/Dynamic_Lighting</a> Light and vision is based on token settings for lighting. From what it sounds like, you have dynamic lighting enabled but no light sources or tokens set up with vision. Also, you may have Fog of War enabled from what you are describing, and not have revealed anything to your players. Hopefully that gives you a place to start troubleshooting. If you can take screenshots and post them (helpful hint - the forum has issues with posting images sometimes, so generally easier to post them on imgur or another photo hosting site and then link them here) of your page settings regarding fog of war and lighting, as well as token settings for lighting, that will also help to figure out what settings might not be correct. Edit to add - if you are using a purchased module, then the pages should be set up correctly for dynamic lighting, which means it is almost certainly something with your token settings.
