I’m trying to manipulate the gizmo in the preview window to adjust the two bone IK positions. The gizmo that should be connected to the left hand has no affect when moving it. It doesn’t even look like it is attached in the right point. I’ve tried disconnecting node going into the Effector Location but it doesn’t help. The preview animation is also paused. Any help would be appreciated.
Ik bones are not usually attached to the mesh.
Read that as “you have the wrong bone selected”
Sorry, I don’t think I’m explaining myself very well. Here is a video of what is happening. I have tried this with the variable going into the Effector Location connected and without. The second is from the Unreal docs showing what the correct behavior should look like. Hope this clarifies my question.
Again, look over your setup. the bones you selected are incorrect.
Also 2 bone Ik does one thing, Fabrik another. you shouldn’t have one after the other. it’s likely that fabric overwrites your 2 bone Ik the way you have it set up.
Hello,
Thank you for sharing the details of the issue.
I have experience working with Unreal Engine animation systems, IK setups, Control Rig, Animation Blueprints, and skeletal mesh troubleshooting, and I’d be happy to take a closer look at what’s happening with your hand IK gizmo.
From your description, it sounds like the effector may not be properly driving the IK chain, there could be a space/bone assignment issue, or the preview setup may not be updating correctly even though the animation is paused. I’d need to inspect the Animation Blueprint, IK node configuration, and the affected skeleton to determine the exact cause.
I’m much more active on Discord than here, so if you’d like a faster discussion, feel free to add me at splendid0001. You can also send screenshots or a short video of the setup, and I’ll review it to see what can be done.
I look forward to hearing from you
Thanks for the response. I am trying to create a left hand IK system that attaches the left hand to a weapon. In every tutorial I’ve seen the Two Bone IK comes before the FABRIK node. After watching the tutorials again I did have some bones out of place. After correcting them the gizmos are now behaving correctly in the preview window and I’m able to adjust the hand and arm correctly. The problem now is trying to drive these two nodes with variables. The blueprint below shows the logic that is driving the variable. This is called every frame through in interface from the animation blueprint

Again:
Fabric does one thing.
Two Bone IK another.
They aren’t supposed to be one after the other.
Not sure how much more clear than that I can get.
