Filters

Filters are tools that adjust positions of an object based on its positions in the neighboring frames. By applying filters you can add inertia to your animations, smooth an object's trajectory, or fix animation errors.

Filters can be used for making quick adjustments to character poses and animation sequences alike.

As of now, filters can only be accessed using hotkeys.

Types of Filters

Attract to previous position

Hotkey: 

This filter moves selected objects closer to their positions in the previous frame.

Attract to inertial position

Hotkey: 

This filter moves selected objects closer to their inertial positions, which are calculated based on the positions in the previous frames.

Attract to average position

Hotkey: 

This filter moves selected objects closer to the average positions of both previous and subsequent frames.

Attract to inverse inertial position

Hotkey: 

This filter moves selected objects closer to their inertial positions, which are calculated based on the positions in the subsequent frames.

Attract to next position

Hotkey: 

Moves selected objects closer to their positions in the next frame.

Attract to interpolation position

Hotkey: 

Moves selected objects closer to the average positions in the nearest frames.

Using Filters

To significantly alter the object’s positions you have to apply filters multiple times or amplify their effects (see below).

Hotkey	Applies a filter to the current frame
Hotkey +	Applies the filter to every frame selected on the Timeline
Hotkey +	The effect of the filter is amplified
Hotkey +  +	Applies the amplified effect to every selected frame

Note: If you apply a filter to an interval, the type of interpolation on this interval will be changed to Fixed.

All these functions are also available as menu items.

Examples of using filters can be seen in our tutorial:
