FX Library
From Roll20 Wiki
 | This is about a Roll20 feature exclusive to Pro-subscribers (and often to players in a Game created by a Pro-subscriber). If you'd like to use this feature, consider upgrading your account. |
Below are a variety of Custom FX parameters developed by Roll20 users to achieve different goals.
Earlier examples only work in the "FX Playground" - the gravity parameters have since been updated to the format "gravity": {"x": 0.01, "y": 0.01}. Making this correction will allow most of these to work. Sharpness appears to be deprecated. FX Playground only examples will be marked as such.
