Greetings! As you may know, we are testing the new Updated Dynamic Lighting system over on the Dev Server . This morning, we pushed code that offers API support for the new Updated Dynamic Lighting options. Details are in the top-level post here . Please note that these API functions are only available on the Dev Server for now. When testing is done and this goes live, it will be put into the API Function Documentation on the Roll20 Help Center. If you have comments or feedback, please drop them in the Pro Forum thread .
