Change Skeleton Asset of Skeletal Mesh

I’m trying to change skeleton from of mesh and then I get broken animation. All animation is in position T. How to do it correctly?

P.S: I added root bone to Adam from Mixamo and I want replace old skeleton, which does not have this bone.

Thanks.

Hi Elias,

I’ve assigned someone to look into this issue for you, and they’ll post here if they require any additional information. Thanks!

Hi Elias,

If you are trying to use UE4 Skeleton and Animations with Mixamo character Adam, please follow instructions on following link:

If this does not answer your question, please add more detailed information about what you are trying to do.

Thanks!

No, that’s not what I do. I downloaded Adam fbx from https://www.mixamo.com/store/. Import it to UE4. I do retarget for both. And I do Assign skeleton. illustration below.

What are two skeleton names you are trying to retarget?

Old Adam Skeleton without root bone = “Adam_1_Skeleton”
New Adam Skeleton WITH root bone (added ) = “?”

“Adam_1_Skeleton” (from fbx) and “Adam_Skeleton” (from mixamo packs)

Here, I did not add a new bone. I did it for example. So you can easily repeat bug.

Hi Elias,

You can retarget two different Mixamo skeletons following link I sent before. However there are some steps that might be confusing that I will try to make clear here.

In my example I retargeted Mixamo Adam to Mixamo Alpha skeletons. To do this you have to first retarget bones to a common humanoid rig as shown:

Adam to Humanoid rig:

Alpha to Humanoid rig:

51970-root2.png

Now select animation you want other skeleton to perform. In this case I want Alpha Skeletal mesh to perform Adam Jump animation:

51971-adamjump.png

Now choose Skeletal mesh you want to copy this animation to:

new animation of Adam Jumping will be copied to Alpha’s animation folder. Now Alpha is performing Adam’s Jump:

Thank you of course, but it was not a problem. I can retarget animation. Actually this is what I have done for my task. problem is that reassign skeleton is not working.

Again:

retarget animation - works
reassign skeleton - has bug

Maybe you want to say that this is not a bug but a feature.

Hi Elias,

Sorry I misunderstood. To assign one skeleton (with no animations, for example) to another skeleton (with animations):

  1. Right click on skeleton with no animations (or make a duplicate and continue)
  2. Choose Assign Skeleton (like you did above)
  3. Select new skeleton (with animations)
  4. You will prompted to save new skeleton -save it
  5. Now click on old skeleton (or duplicate)
  6. Click on animation tab of old/duplicate skeleton and now all animations from skeleton you assigned are available for this skeletal mesh.

I tested these with Mannequin Skeletal (Silver Guty) mesh assinging man skeleton to access Animation Starter Pack with Silver guy.

Result: New Silver guy with assigned skeleton performs animations but arms and legs look pulled out of socket.

Resolution: Recursively Set Translation Retargeting Skeleton under advanced settings as shown:

Many thanks! I will try.
