CREATE ANIMATOR FRIENDLY RIG IN A MINUTES!
Rigger includes the most essential modern techniques for semi-automatic setup: Forward Kinematics (FK), Inverse Kinematics (IK) and Spline Inverse Kinematics (Spline IK).
FK
With FK, you rotate or move individual joints to pose and animate your joint chains. Moving a joint affects that joint and any joints below it in the hierarchy.
IK
With IK, you move an IK handle to pose an entire joint chain. An IK handle is an object you can select and move that affects the joints it is assigned to.
SPLINE IK
Use spline IK for posing and animating long, sinuous joint chains like those for tails, tentacles, snakes, necks, spines, and similar objects.
KEY FEATURES
IK / FK BLENDING
You can pose and animate the joints of a joint chain using both FK and IK. Ik Blend attribute lets you switch between posing and animating with pure FK or pure IK, as well as control the blend between the two kinds of animation.
STRETCHY
Rigger will automate the task of making a joint chain stretchy. With this option the joint chain will stretch when the ik handle is pulled beyond its maximum length.
SCALABLE
It is very important to have a scalable rig that fits into your environment. Rigger automatically creates ready-to-scale modules.
