Stoke MX Field Fluid Motion Modifier

Available in Stoke MX 2.0 and higher. Last Edited on May 1, 2014.


The Stoke Field Fluid Motion modifier can be used to remove the Divergence from Vector fields (typically Velocity fields) coming up the 3ds Max modifier stack.

It is similar to the SimpleFluid operator in Stoke Field Magma, or the Simple Fluid Solver of the Stoke Field Simulator, but can be applied to any Vector field, including one coming from a Stoke Field Loader for example.

It has the added bonus of being easily accessible on the 3ds Max modifier stack for fast toggling on and off.
