Amplifies existing curls to keep them alive longer. When using strong amplification, the curls will get stronger and stronger. After some time the flow may become very noisy. To avoid that, the Intensity Channel and Mapping allow you to restrict the effect of Vorticity to a region that you control using another fluid channel.


Sets the strength of amplification for small curls.

Intensity Channel

You can control the vorticity in space using any of the fluid channels. Use this to amplify the curls only where the temperature is high enough, for example.

Intensity Mapping

For improved control over the intensities, the values of the Intensity Channel are re-mapped by this f-curve before scaling the vorticity.
