What is the purpose of a pole target?
a pole target is a secondary target for a bone with an IK constraint. The first target is where the chain of bones is trying to get to, and the second target(pole target), is where the chain bends to to get to this target.
How to apply constraints after the IK effect?
To apply constraints after IK, it is necessary to first copy the final transformation to a new bone chain, e.g. using Copy Transforms. Data ID used to select the an armature. See common constraint properties for more information. Object for pole rotation. Maximum number of solving iterations. How many bones are included in the IK effect.
Is the IK solver the same as the position and orientation constraint?
If the iTaSC IK Solver is used, the IK Solver Constraint changes to add these addition parameters. Equivalent to the traditional end effector position and orientation constraint: the end effector is constrained to take the position, and optionally the orientation, of a given target, which is set in the target field.
Why does IK control bones bending in the wrong direction?
Hey, In my experience it is usually due to bone alignment when created (Edit mode), but given that you re-built it, that is a conundrum. I mocked up a simple example, as you can see, ‘Armature’ has a bone moved slightly to the left and I changed the ‘Bone Roll’ on it and the next one.
How can I change the rotation of an IK chain?
In pose mode, transform lock all transformations except Y rotation. Optionally, move the new chain parent to a different bone layer. Now, rotate the chain parent to change the rotation of the IK chain. I’d show a pic, but there’s nothing really to show.
What is disable for targetless IK in itasc?
Disable for targetless IK. Chain follows rotation of target. Controls the percentage of affect the constraint has on the object. See common constraint properties for more information. If the iTaSC IK Solver is used, the IK Solver Constraint changes to add these addition parameters.
What makes the IK constraint special in Blender?
The IK constraints are special in that they modify multiple bones. For this reason, they ignore their position in the stack and always run after all other constraints on the affected bones. To apply constraints after IK, it is necessary to first copy the final transformation to a new bone chain, e.g. using Copy Transforms.
