Incidence Falloff

The Incidence Falloff calculates a weight value determined by the incidence between the vertex normal and the falloff locator. If no vertex is provided, the default value of 1.0 is applied.

To activate the Incidence Falloff tool:

1.   Open the Model layout, on the right panel, open the Items tab.
2.   Click the down arrow beside Add Item and select Falloffs > Incidence Falloff.

• Alternatively, open the Setup layout, on the bottom panel, click Add, and select Mesh Operations > Tool Pipe > Falloffs > Incidence Falloff.

Transform Properties

Name

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.

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.

Incidence Falloff Properties

Falloff Enable

Toggles the influence of the falloff on or off. When 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 enabled, 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 are only influenced half as much.

Deformer Enable

When enabled, you can connect the falloff to a mesh and use it as a mesh deformer. For more information, see Applying Deformers.
Angle Defines the threshold angle used to modulate the weight.

Easing Properties

Gradient

Allows you to re-map the weight of a falloff by creating 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 shape.

For more information, see Key Creation.
