Mega Flow

Have you ever wanted to simulate a wind tunnel in your game, or have leaves of snow blow through your village flowing naturally around buildings, speeding up down alley ways or settling slowly in the lee of an obstacle, Lava flowing down a volcano side or Waterfalls cascading over rocks, Or a car stirring up leaves as it drives along a road in Autumn, vortices for your plane wings, perhaps an object floating along fast moving water, tornadoes, or even simulate gravity around objects in space, if so then MegaFlow can help.

MegaFlow is a set of systems that allow you to use Vector Fields to control the movement of objects or particle systems in Unity. Vector fields are a 2D or 3D grids of values that describe the direction and magnitude of velocities for that point in space. The Vector Field can be generated by systems such as Maya Fluids, FumeFX, Krakatoa, RealFlow etc. MegaFlow can import the files generated by those systems in the form of .FXD or .FGA files, it also has an exporter for Maya that will export any Maya fluid simulation to the MegaFlow .FLW format.

You can then import a single frame or multiple frames into the MegaFlow system in Unity and then use that to control the movement of particles from either the Shuriken or Legacy particle system, or control movement of Rigid Bodies or just general objects. Don’t worry though if you don’t have access to any Fluid Simulation software as MegaFlow also comes with a system that allows you to author your own Vector Fields inside Unity using multiple splines to define flow directions and forces.
