Tween Machine

This tool is used for blending the object’s current position with a different position: either taken from other frames or calculated on the basis of these frames.

The Tween Machine can be accessed through the dedicated tab on the Scene Settings panel:

Filter type
Defines the method for blending the frames. Available options are:

  • Previous/Next
  • Inverse/Forward inertial
  • Interpolation/Average

These options are described in greater detail below.

Target
Defines the frames to which tweening is applied.

Current Frame means that tweening is applied exclusively to the current frame (marked by the Current frame indicator)
Selected Frames mean that tweening is applied to every frame in the selected interval.

Slider
This is the main control of the Tween Machine tool. By moving this slider you can mix the current position(s) of the selected objects with two other positions defined by the Filter type settings:

Previous/Next position:

Inverse/Forward inertial:

Interpolation:

Average:

Settings

Various parameters for the Tween Machine can be found under the Tween machine (Advanced) tab on the Scene Settings panel:

Factor
This parameter defines the influence used for pasting the previously copied animation.
The value ranges from 0 to 100.
100 means the copied animation completely overwrites the original, while 0 means that the copied animation is ignored and the original is kept without changes.

Mode
This parameter sets the coordinate system in which filters are applied.
Available options are: Global (world coordinate system is used), Local (object coordinate system is used) and Relative (object coordinates in relation to other objects are used).

Rotate
This parameter defines coordinate axes that can be used to rotate an object when a filter is applied.
There are four possible options: XYZ, and Whole. The latter means all three axes are used.

Position
This parameter defines coordinate axes that can be used to change the position of the object to which a filter is applied.
There are four possible options: XYZ, and XYZ (the latter means all three axes are used).

Scale
This parameter defines coordinate axes that can be used to change an object's scale when a filter is applied.
There are four possible options: XYZ, and XYZ (the latter mean all three axes are used).

All frames/Only key frames
This parameter defines if filters should be applied to all selected frames or only to key frames
