Settings¶

IK Dynamic Settings¶

There are a lot of settings but some of the most relevant are:

Ground
Direct Control
Indirect Control
Use Distance
Duration
Moving Maximum Count
Moving Nearest Count
Velocity Extrapolation Multiplier
Owner Outer Radius
Hit Matrix Maximum Distance
Owner Indirect Control or Direct Control

Note

The word owner in the settings names is the owner pose bone.
Using Undo and Redo when IK Dynamic settings have changed can crash Blender.
Some settings names such as Factor should have a value in the 0.0 and 1.0 range.

Note

The move methods are Float, Constrain and Constrain Normal.
Each move method are enabled with a factor to blend between the move methods. The factor is not a boolean but a value to avoid position snapping.
The move methods blends with each other in a specific order:
- Owner Float or Constrain Factor: when 0.0 uses Float, when 1.0 uses Constrain.
- Owner Constrain or Constrain Normal Factor: when 0.0 uses the move method in Owner Float or Constrain Factor, when 1.0 uses Constrain Normal.

Pose Bone Settings¶

These settings are the same settings in IK Dynamic settings but they are applied per pose bone and not for every pose bone if the toggle with the world icon next to the setting is not enabled.

Not all IK Dynamic settings are available in pose bone settings.

The pose bone settings are shown in the IK Dynamic Pose Bone panel and are the way to input custom settings per pose bone into an IK Dynamic system with the given IK Dynamic Index.

Update Pose Bone IK Dynamic Settings: Automatically update IK Dynamic settings to IK Dynamic. This can be undesirable if there are multiple IK Dynamic systems.

Note

It is recommended to tweak IK Dynamic settings globally to get used to know what settings do what and then tweak per pose bone.
To manually update the pose bone IK Dynamic settings to IK Dynamic if Update Pose Bone IK Dynamic Settings is not enabled, use the operator Apply Pose Bone IK Dynamic Settings.
The settings shown are not necessarily the current pose bone IK Dynamic settings. To update the settings shown, use the operator Read Pose Bone IK Dynamic Settings.

The following settings are only available in the pose bone settings.

Is Owner: Define if the pose bone is owner in IK Dynamic.

Instance Index: Define the order in which the animated pose bones will move.

Start Position: Start position of the pose bone in IK Dynamic.

Start Rotation: Start rotation of the pose bone in IK Dynamic.

Offset Position: Offset position of the pose bone in IK Dynamic.

Note

The settings Is Owner, Start Position and Start Rotation should not be edited. They are edited when using IK Dynamic operators.
