How do I limit the rotation of an IK constrained bone?
As a result of that, it was being forced into odd angles on it’s Z axis far more than it should have been. Now, in order to set pole targets, i put a temporary Pointing bone at the knee/elbow, parented to the lower bone (shin, lower arm) and i adjust the pole angle until this bone points exactly at the pole target
Is there a way to lock a bone axis?
This can prevent a user transforming specific axes. A more rigid approach is to use constraints, There are several limit transform constraints that will prevent bones being moved or rotated outside of your settings. Here you can also set limits, so you can allow a bone to rotate 30 degrees on one axis.
What makes a root bone move in a blender?
A root bone will move everything in the rig.Your hip (or main torso control) should be moving body. If you pull too far away for the limb to reach, it will eventually get pulled off the surface. Just as happens in the real world.
Is it possible to hold on to IK?
Sit in a rolling chair and try to hold onto your desk while someone rolls you away from it. Eventually you won’t be able to hold on no matter how hard you try. IK works the same way. Of course it’s possible, so long as you have a way of defining which constraints have the highest precedence.
How to control the bone roll in Blender?
In Edit Mode, you can control the bone roll (i.e. the rotation around the Y axis of the bone). However, after editing the armature, or when using Euler Rotation , you may want to set the bone roll. Align roll relative to the axis defined by the bone and its parent. Align roll to global X, Y, Z axis.
How can I control the direction of my knee?
Last step is to add Copy Rotation constraint to foot_bone. Now your leg is controlled with the target bone. You can also add a Pole bone for the IK constraint so the direction of the knee is defined:
How is pole target bone extracted from IK chain?
The Pole Target Bone is usually extracted by extrusion from an IK-Chain Bone, just make sure to unparent it from the IK-Chain, if you go that way. You probably want to still keep it parented to your armatures the Root Bone.
What should I do with my elbow controller?
With the elbow pointing in the right direction. So bring the joint back slightly in edit mode. This gives the solver something to work with. Having a slight bend in a chain always works better, even when key framing. Having a completely straight rest pose for your limbs will cause problems.
How does a pole target work in IK?
An IK chain with a pole target is the most user friendly and simple way to get a chain to bend in the direction you want without jerking and popping. It’s the way the IK constraint is designed to work; there’s a field for a pole target right there in the constraint settings.
How does the elbow controller work in Blender?
Now the elbow ik works (so the arm bones rotate in the Y axis, that is an axial rotation), but the arm wont bend, no matter how i move or rotate the hand IK can’t upload more attachments, bu i got it here: http://s000.tinyupload.com/?file_id=06985658329186261846
