Справка Houdini на русском Character Building rigs

Rigging approaches

In Houdini, you can set up characters using two different styles. The two styles both have advantages and disadvantages, and allow different types of convenience.

Simple, default style

The simple style is the style for which Houdini’s UI is optimized: a single end goal for each IK bone chain, and a single IK solver for each bone chain.

Complex, blended style

The complex style involves creating multiple goals for a bone chain that live in different spaces (for example, character space and shoulder space for an arm goal) and blending between them based on how the animator wants to pose at any given moment.

The mechanics of setting up bones with this style are described in blending between multiple IK goals .

Style	Advantages	Disadvantages
Simple	Seamless usability with Pose tool: show blend handle, snap to IK, snap to rotates menu items; "smart" goal snaps to bone end automatically. (See IK/Rotation blending for information about these UI conveniences.) It’s the default: it works as expected without editing. Faster interaction than complex method.	Single end goal means you have to choose one space for it to live in. Can’t pose in different spaces.
Complex	Tremendous control over the space in which you pose each goal. Rig can be adapted to different animation styles.	More difficult to rig. Requires setting up multiple goals and a Blend node to blend between them. Pose tool loses IK/Rotation convenience features (see IK/Rotation blending ). Potentially slower than the simple setup.

Note

For another perspective on rigging style, see posing using temporary IK on building a rig without any IK and using Houdini’s temporary IK feature to pose.
