Add Force Node apply directional force to the Simulation Data.

Input / Simulation Data:
Input simulation data for Add Force. 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.

Defines on/off status for this function.

Intensity [unit / sec^2]:
Defines intensity of the directional force.

Defines direction of the force.

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.
