I want to know why the joints don't work with TwoBoneIK3D

Question

In the image, I created a bone in Blender and then used TwoBoneIK3D on that bone in Godot. The orientation changes, but the joints don’t work.

I asked a question on the official Discord, unchecked LOD and re-imported.
I imported the .blend file into godot and am using it.

What I want to know:

I want to implement IK that bends joints.

What I want to create

I want to recreate the behavior of spider legs.

Godot Version

4.6 C#

OS: windows10

You need to set a different pole node. If target and pole are the same node then nothing will happen.

Thank you.
I set the pole node to Marker3D and the target to Node3D
and tried various things, but nothing changed. Why is this?

It’s hard to tell without any more info. Check this tutorial which talks about how to setup a TwoBoneIK3D node:
