nCloth Force Field Generation attributes

Generates a force field that can push (positive fields) nParticle objects and other nCloth objects away from the current nCloth, and pull (negative fields) nParticle objects and other nCloth objects toward the current nCloth. A Force Field can only be exerted on Nucleus objects that are assigned to the same Nucleus solver as the nCloth object that is generating the Force Field.

See Generate Force Fields with nCloth.

Force Field

Sets the orientation of the Force Field, meaning from which part of the nCloth object the force is generated.

Off

Force Field generation is turned off.

Along Normal

The Force Field is generated from the surface normals of the nCloth object.

Single Sided

The Force Field is generated from the positive normal side of the nCloth object.

Double Sided

The Force Field is generated on both sides of the normal (positive and negative sides) of the nCloth object.

Field Magnitude

Sets the strength of the Force Field. Positive Field Magnitude values push nParticle objects and other nCloth objects away from the current nCloth. Negative Field Magnitude values pull nParticle objects and other nCloth objects toward the current nCloth.

Field Distance

Sets the distance (in field units) from the surface of the force generating nCloth that the Force Field is active. Outside the Field Distance, the Force Field does not affect nParticle objects and other nCloth objects.

Field Scale

Sets a Field Scale ramp that can be used to vary Field Magnitude along the Field Distance. By clicking on the graph and dragging the position markers, you make a curve that defines Field Magnitude for any input value. Selected Position and Selected Value are used to edit the individual curve points.

Selected Position

This value indicates the position of Field Magnitude on the ramp. The left position on ramp represents Field Magnitude along the surface on the nCloth object. The right position on the ramp represents the Field Magnitude at the edge of the Field Distance.

Selected Value

This value indicates the Field Magnitude of the Force Field at the selected position.

Interpolation

Controls the way Field Magnitude blends between positions on the ramp. The default setting is Linear.

None

The Field Scale curve is flat between points.

Linear

The Field Magnitude values are interpolated with a linear curve.

Smooth

The Field Magnitude values are interpolated along a bell curve, so that each value on the ramp dominates the region around it, then blends quickly to the next Field Magnitude value.

Spline

The values are interpolated with a spline curve, taking neighboring indices into account for greater smoothness.

Force Field Maps

Field Magnitude Map Type/ Field Magnitude Map

Field Magnitude Map Type determines the type of Field Magnitude map for this nCloth object. Select None (no map), Per-vertex (map is applied per-vertex), or Texture (uses the texture map specified by the Mass Map attribute).

Field Magnitude Map specifies the texture map used as a Field Magnitude map. This attribute is only available when the Field Magnitude Map Type is set to Texture. Type in a path to a texture file, or click the map button to use a Maya Texture node. See also Field Magnitude.
