RE: Gear IK chain seems to be scaled
OK, now it seems to be an issue with the chain itself. In a brand new scene I created a chain with 3 guide elements. I unhide the deformers group to see the deformers, and when I play with IK/FK blend value, the deformer seems to move along its local X axis. At blending of 1 the deformer is double the distance from its parent than originally Anyone could make me a test?

Re: Gear IK chain seems to be scaled
Hi, Having a quick look at this, and I manage to repro it here. What causes the deformer to move when doing fk-ik blend is the expression that is driving the position of (chain_C0_1_loc etc.. assuming that the bone will translate) is blending between the local position of ik bone that has no neutral pose againts the FK chain controller position that has neutral pose. To fix this, you could try to set neutral translation on the bones of the IK chain. (chain_C0_chain_0_bone etc.. when name is default) considering the deformer parent also has the same neutral pose on it. The other thing that worth mentioning is that the FK chain doesn't seems to align to the IK chain by default, but you should be able to match the rotation easily.
