Motion
Control provides you with a set of often used animation tools.
Blend Motion Cycle
This tool creates a smooth motion cycle for animated translate,
rotate and scale channels using a non destructive blending method.
To create a proper cycle the animation must be extended before
or after the actual motion cycle to have a sufficient blend
range. The original animation curve will not be altered. The
tool creates a duplicate of the animation curve and applies
a time/value offset to achieve the blend effect. A blend curve
is created, that gives you precise control how the two curves
are blended to perform a cycle. Enabling the bake option will
delete all history nodes and finalize the animation. There are
4 predefined tangent types available for the blend curve: linear,
ease in, ease out, ease in/out.
Copy
Motion
Use this tool to copy motion from one part of an animated hierarchy
to another part. Using the time offset and mirror options you
can copy the motion of an animated right arm or leg to the left
side of the skeleton to achieve an equally weighted motion.
If the hierarchy 'below' option is enabled you must make sure
both the source and destination hierachy are exactly identical.
Make sure to check the node order in the Outliner.
Freeze
Motion
This tool freezes a time range of animation curves by deleting
or resetting keys within that range. The animation curve value
from the defined start frame will be used throughout the frozen
range. You can use this tool to stick the feet of a mocap animated
skeleton to the ground for a certain range of frames. This tool
will affect animation curves directly.
Modify
Time/Value
Use this tool to offset and scale the time and/or value of animation
curves. As long as the bake option is disabled the original
animation curve will not be altered.
Anim
Curve Control
This tool provides almost the same functionality like the graph
editor, giving you control of animation curve tangent and infinity
settings. You can affect selected animation curves and keys
directly or select complete node hierarchies.
Adjust
Motion
This tool adds locators to each transform/joint/ik handle node
in the selected hierarchy to adjust transform/rotate/scale animation
curves. You can use the locators to tune i.e. the rotation of
bones derived from mocap data, without altering the original
curve itself.
Bake
Motion
The bake tool is similar to Maya´s 'Bake Simulation' function.
In addition you can bake hierarchical motion to individual locators
using world space coordinates. This way you can convert rotational
hierarchical animations (e.g. derived from Mocap data) into
non hierarchical translations and rotations, that can be used
later on for a mixture of forward/inverse kinematic. |
