Add Wind Node apply wind force to the Simulation Data through Wind and Turbulent Helper Object.

Input / Simulation Data:
Input simulation data for Add Wind. You must connect this input for work.

Input / mask Grid:
Input SDF or Fog grid data for masking. The mask makes gradient effect between min Mask Falloff and max Mask Falloff.
Imported SDF Grid will be convert to Fog grid(surface = 0.0 / deepest = 1.0) and use that value for the gradient and effect.

Output / Simulation Data:
output result simulation data.

on/off:
Defines on/off status for this function.

Pick Wind Helper:
Select Wind Helper object from scene assets.

Make Wind Helper:
Generate Wind Helper object and set it to the node.

Value Type:
Select type of Wind value. Velocity[unit / sec] / Acceleration[unit / sec^2]

Intensity Multiplier:
Defines intensity multiplier value of the wind force.

Pick Turbulence Helper:
Select Turbulence Helper object from scene assets.
If you don’t need turbulence, don’t need to use here.

Make Turbulence Helper:
Generate Turbulence Helper object and set it to the node.

Turbulence Rate:
Defines turbulent rate of the wind. 0.0 means totally direction wind. 1.0 means totally turbulence.

Invert Mask
Inverts the mask.

min Mask Falloff:
Start (or End) Falloff value. If the mask voxel value is smaller than this, full effect.

max Mask Falloff:
End (or Start) Falloff value. If the mask voxel value is larger than this, no effect.
