IK/FK switching problem.

#1

[b]Hi,

I build my IK/FK with three parts:
Ik joints, Fk joints, and binding joints
ik/fk can be switched smoothly.

But when I stretchy Ik joints [size=2](if IK length > sum of joints then scale of joints = IK length / sum of joints)[/b][b] ik/fk blend have some additional rotation.cause my Ik handle is adding rotate values to my Ik joints, and so when I switch from Ik to Fk it not lining up anymore.

what should I do for ik/fk blend be smooth with stretchy Ik joints .

Thanks.

Sorry for my English.

i didnt really understan your problem .
You need to explain us how the bind chain is driven.
For example if you use a blend color node or blentwoAttrobutes node doesnt matter what translate , rotate or scale value the two chains you have the bones will blend correctly .
There are some other variables tho , but before cover them first explain your blending set up pls :slight_smile:
