Animation (Pose) distorted after import from maya to ue4

Hi,

i have a strange issue and i dont know where to find the error.

Here i have an animation, rather a pose:

There are no keyframes, just one value for all transform values:

After import to ue4 i have distortions on the hands:

If anyone has experience about that or had the same issue, pls tell me :slight_smile:

The Anims are not additive, just anims imported with the default settings. The Skeleton is not touched, means all retargeting options are “Animation”, so the mesh should follow the animation.

Yeah, hopefully someone could help me, really drivin me crazy :slight_smile:

Thanks

Best Regards

Check your skin weights around the wrist and forearms looks like another bone is pulling on the mesh in those areas

Hi, thank for the fast reply. I thought so too.

Let me explain it a little bit more detailed.

The Character Mesh is a Mixamo Character. All Mixamo Anims works pretty well with this Character Mesh and its Skeleton. I have slightly modified the Skeleton, added 2 new bones, but they have no Skin Weights, RightHold and LeftHold. Those bones determines, how a Weapon is holded.

This aiming pose comes from a UE4 Mannequin Pose and its Skeleton. I have retargeted those aiming anims to be useable for the Mixamo Skeleton, exported it and imported it into Maya.

Now only those new aiming poses have this distortion on the character mesh.

Must be something with exporting and reimporting with the skeleton edits…have you tried importing the edits into a blank project without the existing skeleton in place?

Where is the animation from? is it from the animation starter pack?

Hi, sry for the late reply. I dont know what skeleton edits are. I am not an Animator Master :slight_smile: I know there is a Mesh, a Skeleton and a Bindpose.

I have uploaded the file. It would be awesome if you have a look onto it. I think you can find the error in 5min. If you need a compensation ,pls tell me.

The original anim comes from rama. he made those aiming anims with the UE4 Mannequin. I just retargeted it to the Mixamo Skeleton

Yeah, that looks much better. what do i have to do to achieve this result.
Rotating Wrist?

It is definitely the skin weights around the wrist and the lack of support loops around the wrist to allow for the movement of the wrist correctly.

The Mixamo animations have the same results as retargeting the animations from UE4 mannequin (above is a direct retarget of the ASP animation to the Ely character)

That is a retarget from the ASP animation idle_rifle_ironsights

As a bonus here’s a pack of working animations for the Ely character:

Thats awesome. Thank you very much.
