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, make object trajectory more smooth and fluid, fix animation errors.

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

Filters can be selected from the Filters menu at the top of the program window. However, as adjusting poses and animations often requires applying a filter a number of times, more efficient way of accessing them is by using hot keys.

Types of Filters

Attract to previous position

Hot key: 

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

Attract to inertial position

Hot key: 

This filter moves selected objects closer to their inertial positions calculated on the basis of their positions in the previous frames.

Attract to average position

Hot key: 

This filter moves selected objects closer to intermediate positions between their positions in both previous and subsequent frames.

Attract to inverse inertial position

Hot key: 

This filter moves selected objects closer to their inertial positions calculated on the basis of their positions in the subsequent frames.

Attract to next position

Hot key: 

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

Attract to interpolation position

Hot key: 

Moves selected objects closer to the positions calculated as an average of their positions in the nearest frames.

Attract to local interpolation position

Hot key: 

Moves selected objects closer to the positions calculated in local coordinates as an average of their positions in the nearest frames.

Angular momentum

Hot key: 

This filter alters character's angular momentum in the current frame to make it closer to the average momentum calculated on the basis of the momentum in other frames

Using Filters

Applying a filter one time will only have a minimal effect on the selected objects. To significantly alter object positions you have to apply filters multiple times or amplify their effects (see below).

By simply pressing the hot key assigned to a filter you apply that filter to the curent frame. By pressing the hot key while holding  you apply the filter to every frame selected on the Timeline.

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

If you press the hot key while holding  ,  the effect of the filter will be amplified. By holding  and  at the same time you can apply this amplified effect to every selected frame.

All these functions are also available as menu items.

Examples of using filters can be seen in our tutorial:
