Ultra Volumetrics is a simple way to add more visually interesting game-ready and performant local volumetric fog to any project! With many adjustable parameters and functions for ease of use. With the built-in Paint Mode, you can paint fog where you want it and make it move in any direction. Utilize the power of splines to easily place fog exactly where you want very rapidly without losing functionality and easily animate it. Mix multiple Ultra Volumetrics volumes to create interesting effects. Interact with the fog as a player or physics object and generate overlap events.

Create stunning fog that clings to surfaces with distance fields, and with the included randomize function, it is incredibly easy but more importantly fast to dress up levels and scenes with various volumetric fog effects. Choose from the included presets or save your own custom preset to easily use it elsewhere.
