Mixamo Animation Retargeting

Snip, Sorry, fixed it.

Edit:
Actually, another issue just came up. Any idea what could be causing the models head to rotate into its chest as the base skeleton?

Thanks, again…

Hi. Never seen that Does this happens after having used our plugin? Or before, soon after the import in UE4?

If it happens with our plugin:

1. Workaround: you can manually correct the retargeting pose, save it, and use the correct retargeting pose before doing any animation retargeting.
2. If you could share the source asset with us, PM me. So we can look at the problem.

Thanks for the timely response, and yes this happens after hitting “re target Mixamo skeleton” … Setting the show setting to the mannequin pose makes the head rotate into it’s chest.
By manually correcting you mean to just do this within Unreal itself?

Thanks.

Alright, so removing all the skeletons and reimporting them again and they worked flawlessly this time, seems to have been some kind of bug that cropped up somewhere along the way. Can’t say exactly how to reproduce it but all is working now, thanks for the software

Happy you solved!

I’ve reproduced bug in clear project with freshly downloaded mixamo char and anims, and UE anims from pushable asset

My actual mixamo skeleton is taken from regular exported FBX, no matter with old mixamo exports for UE4 - i completely changed all animations when mixamo deleted UE support.

It’s definitely a problem of old unreal animations, lacking something that epic fixed few patches ago, and nothing more.

@Voradori Hi Can you let me know which old packs are affected, as I have several that I have not started using yet and will also contact the asset pack author to implement the fix, thanks.

It’s a “known problem” with Mixamo: its materials are imported as translucents also if they are not. Usually forcing the materials that are not using transparencies to “opaque” should fix the issue.

Here a more articulated comment found recently on Facebook (Redirecting...):

Thanks that worked perfectly.

does this add the IK joints as well? i need to know this before i buy this.

Dipping bug affected Pushable Blocks asset anims. It’s fixed, and no other cases found for now.

Hi! Not at the moment unfortunately. Maybe we’ll add this feature in the future, but we don’t have an ETA at the moment.

(I didn’t tested it - so this could not apply) Maybe you can add the IK bones directly in UE4, as virtual bones?

Followed the instructions, the retarget Mixamo skeleton asset seems to work good, but when I try to retarget an animation the source is empty?

[Cmcginn]

Nevermind. From the source Sk I had to click preview mesh and click on the SKmesh.

Hi, no problem

Unfortunately - at the moment - Mixamo animations can’t be used as root motion animations, here more details: Mixamo Animation Retargeting - Marketplace - Epic Developer Community Forums . Shortly: they don’t embed the informations needed by Unreal Engine 4.

Using the plugin, you can add add the root bone and use any UE4 root motion animation with the Mixamo characters.

Having trouble…

I currently have a project in version 4.12.5 (cannot upgrade since it would cause issues with existing code)

I purchased the plugin and installed 4.16 (and 4.14) thinking I could migrate the new targeted “skeleton.uasset” to my existing 4.12.5 version project… however I cannot seem to migrate the new targeted skeleton.uasset to my 4.12.5 version. (it shows the file migrated folder if I look in windows but when looking at the folder in the unreal editor it shows nothing in the folder.

I installed version 4.14 too - thinking maybe it being closer in versions it would work… but doesn’t work either.

In addition to Migrating… I also tried “exporting” the skeleton - but creates a skeleton.COPY text file (not sure if theres away to get that to work - needs to be renamed? or changed a little to get it to work in another version?)

Any suggestions on how I can get the new skeleton into my 4.12.5 version?

is there a way to export it through fbx and bring it back in?

is there a way to edit the skeleton.uasset file (I opened it in notepad and can see the version - not sure if its setup to never work with previous engines?)

Thanks

Hi,

I successfully tested the “migration” process from UE4.16 to UE4.7 (!):

1. from your source project (UE4.16), select the asset you want to migrate
2. right clink on it, then select “Asset Actions” > “Migrate…”
3. a recap of what assets will be migrated is show, click “Ok”
4. navigate to your target project (UE4.12) and select the “Content” directory, then press “Select Folder”
5. the message “Content migration completed successfully!” appears
6. go to your UE4.12 project and you’ll find all the migrated assets (in the same directory names as in the source project)

I also tested the migration of the “skeleton” asset only (again from UE4.16 to UE4.7), and it works. Of course if you try to open the skeleton in the destination project, you’ll see nothing - as the skeleton has no mesh, it’s only a hierarchy of bone names. If you migrate the character skeletal mesh instead, you’ll end with both the skeleton and the mesh available in the target project.

Ahoy! Firstly, thanks very much for this asset. I’m having a bit of an issue getting up and running. Using the video instructions, after retargeting my mixamo skeleton to the humanoid UE4 mannequin skeleton, the problem arises when I duplicate and retarget an animation blueprint to my converted mixamo skeleton. The animBPs I’ve tried have been for marketplace assets that also use the default UE4 mannequin, and the result is the animations showing the converted mixamo skeleton’s arms inverted and behind the torso (almost like handcuffed behind his back). Any clues as to what could be happening with this? I’m exporting my rigged mixamo character as default FBX in T-Pose and importing the FBX using default settings (at least it should be).

[Piepants]

To be a bit more specific, I’m having this issue with arms folding behind the back after reatargeting/duplicating animBPs from Kubold’s animset movement pro pack and the advanced locomotion r2 pack, which as far as I know are also targeted at the default ue4 humanoid mannequin.

Hi! Two questions:

1. Does the retargeted animations play correctly outside of your animation blueprint?
2. Have you tried using them in a new, simpler animation blueprint?

Maybe there is something in the original animation blueprint that doesn’t play well with the retargeted skeleton/animations.

[Piepants]

Hey!

1. The individual retargeted animations that were duplicated over have the issue, like I can see the arms folded behind the character in each of the animation thumbnails.

2. I did try retargeting the AnimBP from the UE4 sample animations package and the animations seem correct (they’re all holding a gun).

So maybe somehow the skeleton used for the AnimBPs I’m retargeting from Kubold’s animset and the advanced locomotion system are not identical the the skeleton used in the UE4 sample animations package?

[Piepants]

Hmm one thought, could there be an issue of doing the mixamo retargeting with A-Pose and the animBP having been created from a UE4 mannequin in T-Pose? I don’t really know what I’m talking about, but it does seem that the issue is only with the arms, the rest of the body is perfect.
