Bones moving when I try to anchor them to sockets using the two bones IK node. Is it legal?...

Hi, guys! 2 bones IK not working correctly.

1. Each tick Player_BP send the socket location in world space to my animation BP (I draw debug sphere - I see where is the socket in fact)
2. Bone must be anchored to this location by 2 bones IK node (effector - world space). But it isn’t! Why? I can’t understand why the bone moving when I move a character?

P.S. I tried to use other spaces, but I don’t know, how to transform the socket location in world space / component space / other spaces to correct space of bone. I’m event not sure that it is possible at all… Could you please explain a bit?.. Or al least some link to read / watch info… Thanks in advance!

I’ve added some screenshots. The green sphere is socket location (bow string middle point). And it works fine if the character is just standing

But once I try to rotate some spine bone I get this:

And that’s how I rotate bones…

Why IK not working correctly? What’s my mistake?

I’ve found a solution! It’s necessary to transform bones FIRST, and only then to apply two bones IK
