Capsule Falloff

The Capsule Falloff produces an attenuation area shaped as a cylinder with rounded ends. It has options for you to adjust the size, the shape, and the transition of the falloff itself.

Transform Properties

Name

This displays the current item's name. You may change it by clicking the current name and typing a new name.

Position XYZ

Specify to position the item numerically in XYZ space. Position transforms originate from the Center position.

Rotation XYZ

Specify to set the rotation of the item numerically. Rotation transforms originate from the Center position.

Order

Sets the order that Modo applies rotations to the falloff item. By changing the order that Modo applies rotations you can sometimes reduce or eliminate gimbal lock.

Scale XYZ

Sets the size of the item numerically. Scale transforms originate from the Center position.

Reset

Resets the selected transform values to (0,0,0) and returns the items back to their default state.

Zero

Resets the selected transform property value to 0 and leaves the Center position and Item position intact.

Add

Use to add the selected set of transforms to the Channel list while keeping the default 0,0,0 values. (Keeping the default values is necessary for Referencing. To be able to override a channel, it must first exist.)

Note:  Transform items are the channel groups associated with an item that store its transform values. These transform values control an item's position, rotation, or scale. By default, new items do not have any transform items associated with them (although they are visible within the Properties panel). Add only the necessary transforms on an as-needed basis to reduce scene overhead. If you don't use the Add function (as given here), you can transform the target item with one of the various transform tools (or by editing the values). When you do so, Modo automatically adds the transform item to the Channels viewport list.

Capsule Falloff Properties

Falloff Enable

Toggles the influence of the falloff on or off. When clear (disabled), the falloff has no effect on its target. However, Modo saves disabled layers with the scene, and the values persist across Modo sessions.

Invert

When selected, reverses the influence area of the falloff.

Strength

Controls the maximum amount of influence the falloff has on its target. At a value of 50%, even areas that are affected fully by the falloff, would only be influenced half as much.

Deformer Enable

When selected (enabled), you can connect the falloff to a mesh and use it as a mesh deformer. You can specify the initial rest state for the deformer if you select Setup Range as well and position the falloff appropriately.

Setup Range

Determines how the Deformer Enable option affects the target. When using the falloff as a deformer, use the Setup Range to determine the undeformed position for the falloff by using the Setup state. You enter the Setup state and position the falloff where you want the Deformation to originate from. Once you exit Setup, moving the falloff deforms only those vertices within its area of influence from the Setup position. When you disable Setup Range and animate the falloff or mesh, the vertices within its influence are affected, but they slide through the area of influence instead of being affected by it directly.

Axis

Determines the initial axis direction of the Capsule shape.

Length

Determines the extent of the capsule shape from end to end.

Bias

Normally, the Center of influence is directly between the start and end points of the Capsule. Modo uses the Bias value to shift the center toward the Start side of the Capsule with positive values and toward the End side with negative ones.

Start Radius

Specifies the radius of the beginning section of the Capsule from its center line to its outside perimeter.

End Radius

Specifies the radius of the terminating section of the Capsule from its center line to its outside perimeter.

Solid Core

Generally, the falloff's influence attenuates from the Capsule's center line toward its outer edge. The Solid Core value, as a percentage of the total size of the Capsule's shape, defines an inner range where the falloff's influence is at a maximum amount.

Decay Shape

Controls the rate of attenuation across the falloff with three possible choices.

• Smooth - Smoothly fades the strength of the falloff between the Solid Core setting and the Radius of the Capsule Falloff item.

• Inverse Power - Applies a user-controllable curve function to attenuate the value between a linear type falloff to an abrupt, hard-edged one. This decay shape uses the Inverse Power value.

• Gaussian - Smoothly applies the falloff with the greatest influence in the center, which attenuates and terminates outside the falloff's radius.

Inverse Power

If you select Inverse Power as the Decay Shape, this value determines the sharpness of the falloff's attenuation. A low value is similar to an almost linear type of falloff.

Easing Properties

Gradient

Allows you to re-map the weight of a falloff by altering the strength to create a new custom falloff shape. In the Graph Editor, press Ctrl/Cmd + Alt and click on the graph line to add a new key point. Move the key points to create custom falloff shapes.
