Editing the Frame and Joint values¶

Observe and test

Use …	To edit …	How …
Inspector	Frame and Joint values.	Enter a value.
Dopesheet view	Frame values.	Drag the key horizontally.
Robot 3D view	Joint values.	Drag the sliders or drag the wheels.
Curves view	Frame and Joint values.	Drag the key horizontally and vertically. Tip: you can hold the Shift key while dragging a key: it will make the key stick to an axis.

Selecting key(s)¶

To select …	Result
A key Click on it.
Several keys Drag the mouse around the keys to select. Note Tip: to easily select one limb, think about hiding the others.
A whole sequence Drag the mouse on the Frame axis. A blue bar surrounded by red triangles materializes the selection. Note Tip: the shortcut R switches the selection type between Keys and Sequence selection.

To select …

Result

A key

Click on it.

Several keys

Drag the mouse around the keys to select.

Note

Tip: to easily select one limb, think about hiding the others.

A whole sequence

Drag the mouse on the Frame axis.

A blue bar surrounded by red triangles materializes the selection.

Note

Tip: the shortcut R switches the selection type between Keys and Sequence selection.

Adjusting the speed of a sequence¶

To modify the speed of a movement, reduce or increase the number of time frames between 2 Keys.

To modify a sequence of Keys:

Step

Action

On the Frame axis, drag the mouse to select a part of the animation.

A blue bar surrounded by red triangles materializes the selection.

Drag one of the red triangle to condense or expand the selected part.

Tip: hold CRTL key to shift the end of the animation.

Note

Keys can only slip on an empty frame, existing keys are blocking obstacles, unless you hold CRTL key to shift the end of the animation.

Moving a sequence¶

To move a sequence of Keys:

Step	Action
	On the Frame axis, select a sequence of Key.
	Drag the blue bar in order to move the selection.

Cut, Copy, Paste, or Delete key(s)¶

Step	Action
	Select one or several key(s), on the Dopesheet view or on the Curves view.
	Right click to display the contextual menu and choose Cut, Copy, or Delete.

Flip command¶

The Flip command applies on selected key(s).

The flip is performed on the Left/Right axis.

on Arms, the flip exchanges the keys between the two arms.
on Head and Leg, the flip inverts the movement on the Left/Right axis or does nothing if the movement is not on the Left/Right axis.

Mirror command¶

The Mirror command duplicates the selected key(s), from left to right or from right to left.

There is also a Mirror Mode, for further details, see: Mirror Mode.

Tuning curve interpolations¶

By default, the interpolation between two keys is automatically calculated, using the method: Bezier automatic.

It is possible to choose another method, and to tune manually the tangents.

Choosing an interpolation method¶

To set an interpolation method, use:

the toolbar of the Curves view, to set the same interpolation type on the both sides of the selected key.
the Inspector, to set each tangent independently.

Configuring Tangents¶

When selecting an interpolation type, if the tangents are configurable, then black handles appear.

Configurable tangents

appears in black.
Drag the handle to set the tangent offset and ratio.

Non configurable tangents

by default do not appear.
Click the Show all tangents button:

the non configurable tangents appear in blue.

List of Interpolation types¶

Bezier Automatic	Bezier interpolation - non configurable. This is the default mode for new keys. The curve parameters are computed automatically in order to give smooth and good looking movements.
Bezier	Configurable Bezier interpolation. Two tangent handles appears next to the key to control the curve slope.
Linear	Linear interpolation - non configurable. the value is interpolated linearly toward the next key.
Bezier Smooth	Configurable Bezier interpolation, with Colinear tangents. Two tangent handles appears next to the key to control the curve slope. When handled: the two tangents of the key stay aligned.
Bezier Symmetrical	Configurable Bezier interpolation, with Symmetrical tangents. Two tangent handles appears next to the key to control the curve slope. When handled: the two tangents of the key stay aligned, i.e. moving one tangent also moves the other. the length of the two key tangents keep the same ratio relative to the curve.
