Add Wind Node apply wind force to the Simulation Data.
Input / Simulation Data:
Input simulation data for Add Wind. You must connect this input for work.
Input / mask Grid:
Input simulation data for masking. The mask makes gradient effect between min Mask Falloff and max Mask Falloff.
Input 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.
Pick Wind Helper:
Select Wind Helper object from 3dsmax.
Make Wind Helper:
Generate Wind Helper object and set it to the node.
Wind Speed [unit / sec]:
Defines speed of the wind force.
When checked, The added force is limited to wind speed. If the voxel has a velocity faster than the value, no force will be added any more.
Defines turbulent rate of the wind.
Defines directional rate of the turbulence.
Defines scale of the turbulence noise.
Defines detail of the turbulence noise.
Defines phase intensity of the turbulence. Larger value makes faster noise phase animation. Zero makes none animation.
Defines phase offset of the turbulence noise.
Inverts the mask.
min Mask Falloff:
Start (or End) Falloff and use this value if the mask voxel value is more than it.
max Mask Falloff:
End (or Start) Falloff and use this value if the mask voxel value is less than it.
