FumeFX Wind

 

 

This space warp modifier was created because of the need for more flexible and intuitive wind force inside the 3ds max.

 

In addition to 3ds max wind, the FumeFX Wind has the falloff applied to the turbulent force and adds options such as falloff ranges, several falloff types and visualization of the wind force.

 

 

 

 

 

 

 

Force

Strength - The strength of the directional wind component. Values less that 0.0 will invert the direction on the wind.

 

Planar/Spherical - Two possible wind types.

 

 

Wind

Turbulence - Strength of the turbulent component which is calculated by using the Perlin noise algorithm.

 

Frequency - Value greater than 0.0 will cause turbulence to change over time. Smaller value will produce slowly changing turbulence.

 

Scale - Turbulent noise scale. Small values will produce smoother noise pattern.

 

 

Falloff

 

Type - FumeFX Wind supports several falloff types.

  • None - Wind strength will not vary with distance from emitter.
  • Decay - the same as with 3ds max wind force
  • Linear - strength will linearly decrease between ranges defined by the Start and End parameters
  • Exponential - strength will exponentially decrease between ranges defined by the Start and End parameters.

 

Decay - the rate at which the force will decrease by the distance

 

Start - Falloff range start

 

End - Falloff range end

 

 

Display

 

Icon Size - FumeFX Wind icon size in viewport

 

Visualize Wind - Enabling this option allows all the wind parameters to be visualized directly inside the 3ds Max viewport. Forces are displayed on two perpendicular planes which position can be manually adjusted.

 

X Pos - Position of the first visualization plane.

 

Y Pos - Position of the second visualization plane.

 

Density - Determines how dense the display vectors will be.

 

Scale - The force vector scale factor. It does not have the influence on the actual force, but it's used only for visualization.
