I'm not a Blender expert but I followed your directions. I'm getting a warning saying I need Blender 2.8x our better to use the add-on, but I'm using 2.81a.

The add-on is supposedly activated but it's not showing up anywhere in the appropriate menu. Please advise if this is an issue or user error. Thanks

The left foot bone is upside down after conversion.
To fix it I have to reimport the mesh file, set the roll value of the left foot bone to -180 and export/overwrite the mesh file.

Hello, Im still new to using this but im getting a weird leg rotation on Mixamo ANMI when I import them.

It seems like the right leg is always twisted inside out and the rotations throughout the Animation are messed up. but only for that leg

AS unreal engine user
I WANT TO convert bones names to unreal ones.
SO THAT re-targeting animations can be done with a simple click.

Reference for mapping mixamo bones to the unreal skeleton can be found here:
https://docs.unrealengine.com/latest/INT/Engine/Animation/RetargetingDifferentSkeletons/

Am I missing something here? Is there a certain naming convention the anims need to have for it to work?

AS user
I WANT TO have mixamo_converter able to deal with bones prefixed with "mixamorig_" beside the standard "mixamorig:"
SO THAT the converter can handle mixamo skeleton in collada files too.

Why collada? Mixamo exports characters and animations to FBX and DAE (collada) files.
Collada files have correct vertex weights, FBX do not (see story #11).
Bones in FBX are prefixed with the string "mixamorig:" and in DAE files they start with string "mixamorig_"

I couldnt get the converter to work in Blender 2.8, so i reinstalled 2.79 and this is the error i get when I batch convert either a Fuse Character rigged in Mixamo or if I use a Mixamo Character.

Since the plugin doesn't work in 2.81a, I fired up my 2.80 copy of blender and tried to convert an animation.

I get the following error with the selected settings:

What is a problem? Please, help.

I've found a link to have blender's plugin compatible 2.7 and 2.8.
See https://theduckcow.com/2019/update-addons-both-blender-28-and-27-support/

In Mixamoconv file hipname is a byte string and it cannot be use to search in the dictionary.
hips = root.pose.bones.get(hipname)
This trigger an exception.

Hi, I found a problem with this add-on. I am using the add-on to create a root bone to the skeletal mesh rig abd the animations. However in Unreal Engine 4.16 the character is scaled up to a giant when I enable root motion. Is there any specific export settings I have to use?

Hi,To be 100% fair this might not be a problem with this addon, I am a total novice with animations.

I have converted a mesh from Mixamo, and 3 animations, all the animations begin with a T-Pose in UE4.23 when I am previewing them. Maybe this is normal, or a UE4.23 thing, or maybe it is how Mixamo exports them, but the Animations on Mixamo website don't begin with T Pose.

Apologies if this is not an issue with the addon.

Hello !

First of, thanks a lot for this addon, it could really save me a lot of time! I followed the video tutorial but upon batch converting the T-Pose file I get this message in the console:

Traceback (most recent call last):

Any idea what could cause this ? I am under the impression that the spaces in the User directory may be the cause but I don't want to format everything without being 100% sure.

Thanks in advance for the help !

Same files as our previous issue. The hips are now converting flawlessly. Now it is the foot LOL.

correct animation mirroring for turn walkcycles

• turn in other direction, but start with same leg and arm
  hard to implement

in blender 2.8, there is no tool shelve and i can not use this plugin.

I tried it and I tried doing it in many different ways. Please make more detailed instructions or a video (preferably start from download settings on the Mixamo website and end with a working root motion animation from Mixamo). I understood how to do the blender part but when I get to Unreal Engine I have no idea how to proceed. Thanks in advance. <3

at the moment, a single conversion leaves some actions of temporary helper objects in memory which can end up in exported fbx

I know an issue was already opened for this but there was not a useful answer. When I click batch convert after specifying input and output location it gives me the 'Hips not found' error.

Simple

just remove everything before first colon if there is one

Advanced

• detect namespaces and display them in a tree structure
• delete, merge and rename namespaces

Hi,
For about a month I tried to fix a problem with the bones but couldn't find any solution.

So here are some screenshots of the path I used to get this problem

First I download in Collada (Same with fbx. I used Collada because somethings I get a fail message with fbx)

Then I set everything right and remove Auto Bone Orientation

I import and link it to the UE4 skeleton

And here's the problem

Exactly the same result with Automatic Bone Orientation "on".

So now I don't know if it's my mistake or if it comes from the code.
Thanks!

hi there.
I recently used a plug-in for resource conversion and the following error "hips not found"

Hi,
I tried the latest version of this converter and the mesh gets flattened close to elbows during animations.
This issue is not visible if I import the FBX straight from mixamo.
Any idea on what's wrong?

Here is another model which shows the same problem between arm and forearm

Here is the problem shown in blender

Mixamo converter crashes when converting old mixamo animations.

I can't enable this under 2.81a. Using enziop/mixamo_converter/tree/blender28

When I do I get an error, screenshot attached.

at the end of my exception stack:

When I want to add root motion to my collada formated animation I get an fbx output for some reason.

When I try to convert it says the directory name is invalid: "c:\\Users\\UserName\\location"
I am using Blender 2.78. And the model I wanted to convert is in fbx format.

Hey after trying to install the addon for Blender 2.80 I saw it doesn't work. Could you please add support to it?

Example:
The Z axis portion of the Pelvis goes from 0 to -179 so it rotates almost 180 degrees when viewing in the Unreal Engine. This only happens in a few animations that have twisting flips or one that has a flip into a kick. The rest of the animations work great, even the forward flips and rolls, but these seem to constantly twist out.

I am using a FUSE autorigged character.

Vid:

https://youtu.be/E8zwrnHPY0Q

Steps to reproduce this bug:
From mixamo select passive marked man character and T pose.
Download a collada file and try to batch convert it.
The plugin crashes.

Problem:
The armature to convert is "armature3" and "armature" is converted instead.

Workaround:
Import the collada file in blender. Select the "armature3" and click single convert. done.

I can see the plugin in Preference -> Add Ons, with a warning upgrade to 2.8x required, I am using 2.80 only ?

I don't see Mixamo anywhere in my 3D views. Please suggest.

The Animation is fine UE4 and Blender. When Root motion is enabled in UE4 the animation 'glitches' around the same time near the end of animations. Only seems to occur with animations with rotation. Running animations are fine with root motion. A root bone is present after conversion.

I have attached the TPose and rolling animation for the:
original files (.../Root Rotation glitch v1)
Converted with root motion disabled (...\Root Rotation glitch v1\Converted (With rotation disabled))
Converted with root motion enabled (...\Root Rotation glitch v1\Converted (With rotation enabled))

I have an issue whenever I try to batch convert an fbx file. It reads the path with double (//) instead of a single (/). Any ideas on how to fix it?

First, I would like to thank you very much for creating this Blender add-on. It really makes retargeting animations easy.

I've managed to successfully retarget a mixamo character to UE4 human rig. I've also retargeted several Third Person Animations to this new skeleton and I think they work perfectly. This are the main steps I followed:

• Downloaded xbot female in T-Pose

• Used the Convert SIngle option for converting rig

• Also clicked on Use Unreal Engine bone names
  

• I imported this mesh skeleton, performed the retargeting process including retargeting the third person animations. Things worked perfectly up-to here:
  

The next section is where am having difficulty.

I did a batch conversion of the animations that I downloaded from Mixamo website. Just to confirm the conversion worked, I opened one of the output fbx animation files in Blender. Indeed, the bones were renamed as expected(including root) and the animation was working perfectly fine.

Unfortunately, when I import this converted animation to Unreal, I get this weird result that reminds me of the movie "The Thing":

Would you happen to know what I did wrong or if you have a solution for this. Thanks

I'm trying to convert a batch of animations from Mixamo and it's giving me this error.

A few keyframes near the end of every animation glitch out when "Transfer Rotation" is selected.

I'm using Blender 2.79b

i have a problem

has to be checked how root motion is done in different animation databases
then maybe implement preset dropdown for different sources

if you export a rig without bindmesh, the restpose is not saved, resulting in wrong animations
solutioion: check if rig already has a bindmesh, and if it doesn't, add a simple dummy bindmesh
