Well. As you can see, those two bone have IK, but when I move the IK, the two bone didn't move at all. Even if I delete that IK and created a totally new IK for those two bone, it didn't work, the two bone still didn't move at all. And this issue happen alot in my work file as you can see.
Some of my IK work well. and the other Error IK didn't work at all, You can check out the file to see it yourself.
