Falloff

General

Everywhere an effect has a spatial expanse it can be helpful to have it begin either abruptly or incrementally when elements enter its field of influence (in the following referred to as "field of influence"). With exception of the shape of this field, this is exactly what the parameters in the Falloff tab do.

Falloff effects can affect the following elements:

Don’t let it bother you that most of the following examples were created using MoGraph Effectors. This way the mode of operation of the Falloff parameter can be better demonstrated, e.g., using Particles.

Contrary to the MoGraph Effectors for which, for example, the falloff effect takes place on deminishing clone expansion and position, the falloff effect for particle modifiers affects the force field, and for deformers it affects the deminishing movement of object points.

The falloff of a spherical MoGraph Effector. The actual falloff begins outside of the red radii.

The range of an Effector’s field of influence is displayed using the following colors:

Example: MoGraph Effector

If you animate an Effector to pass through a group of clones, the falloff settings can be used to create soft transitions between areas not affected by the Effector and areas affected by the Effector.

An animated Effector with properly adjusted falloff settings results in a uniform displacement as it passes through a group of clones.

Shape

Clockwise from the top left: Box, Sphere, Cylinder, Linear, Source (spline), Source (particle).

The Shape defines the shape the field of influence will have.

You can select from the following:

Infinite

No falloff will be applied to the strength of the field of influence. The Effector will affect the entire scene with full strength.

Box, Sphere, Cylinder, Cone, Torus

The corresponding shape will result.

None

This option only affects the Joint object. If None is selected, the Joint object will have no falloff.

Linear

Falloff will take place along the field of influence’s Z length. The following applies: Full strength in the negative Z direction, no strength in the positive Z direction.

Source

Basically Splines, particles or polygonal objects can be used and the effect will take place within a certain distance surrounding the spline or particle (or around the object points in the case of polygonal objects). See for details.

Invert

Inverts the falloff. Regions with a maximum effect will be given a minimum effect and vice-versa.

Visible

Use this setting to turn the field of influence visible radius on or off.

Sample Distance

Example of a MoGraph falloff with a Spline. Left: lower Sample Distance value; center: higher Sample Distance value; right: Sample Distance with Particles.

This value defines the radius of a volumetric space around each object (Particle, Spline, Clone, object point). The field of influence affects this space and the Clones within it.

Link

Drag the object with which the field of influence should be defined into this field. Currently one of the following can be used:

Sample Detail

For Splines: Sample Detail defines the accuracy with which the sample points will emulate the shape of the Spline. Very large values will take longer to calculate but will replicate the shape of the spline exactly.
