Problem with the head in Maya

anonymous_user_4f03f5c6 · April 16, 2021, 2:53pm

Hi!

First of all, thank you for your amazing work

I need the Metahuman rig in Maya but I can’t get a working file. I tried changing multiple settings in the download/export options in Bridge, tried with different versions of Maya from 2018 to 2022, and I changed my character to be bold just in case… but I always get the same result:

The version I’m using of Bridge is 2021.0.0 and the Bridge Plugin for Maya is version 6.4.

Looking in the SourceAssets folder of the metahuman, there’s only a Maya file for the body. I don’t know if this could be the issue:

Thanks for your help and sorry for the inconvenience!

I have the same problem as you。

I’m having this issue as well. Comparing to the steps listed here:

it looks like I am not getting the Maya import prompt at step #7, and Bridge is only creating the base body .ma file.

Edit: I tried again and the Maya import prompt appeared, allowing it to generate the full_rig.mb file. This may have been a user error on my part the first time. Hope this helps someone!

I’m using maya 2020, and having the same issues. I see the body rig, but not a face rig. I have the DNA files, but not UFC node on the mesh to move the mesh

Same problem here, tried every build of Maya 2020…

In order to assemble the character in Maya please refer to this document.

https://docs.metahuman.unrealengine.com/en-US/HowTos/ExportingMetaHumans/ExportingToMaya/

Supported Maya versions are 2018, 2019 and 2020.

This problem with detached head is usually reflected when only UAssets are downloaded.
In order to download source assets, go to Quixel Bridge and mark UAsset + Source Asset option in the drop down menu (refer to document above under number 6.) and download the archive again
Newly downloaded archive will contain additional files that are required for Maya export.

There is a known issue when export to Maya will not work if your Windows language is not English (that is an issue that is currently being tracked).

Go to control panel
Select region
Select administrative
Select English

If this does not help please provide the log from script editor, so we can track the issue better.

Hi,

I have download settings set to UAsset + Source Asset. Log attached.

It looks like it needs the Arnold plug-in…?

I will dig deeper into this issue. First of all I will need to find a way how to reproduce it. Thanks for sharing the logs its really helpful

Martin_Bell · April 20, 2021, 4:09pm

Hiya,

I installed the trial of Arnold and it works now…!

anonymous_user_982cfb951 · April 21, 2021, 8:05am

Awesome, glad that it worked for you. Regarding Arnold - this is something we should look up into during the cleanup process and preparation of a next build.

Thanks for the info, this was really helpful.
Enjoy using metahumans

anonymous_user_4f03f5c6 · April 21, 2021, 8:32am

It does work! I installed Arnold and now everything works as expected.

Thanks

Martin_Bell · April 21, 2021, 2:35pm

Haha, yes please, I don’t want to have to buy Arnold to use free metahumans

@anonymous_user_4f03f5c6 No worries, just glad to get it working!

NodeBlaster · April 22, 2021, 11:13am

Finally got the export into Maya working. Having Arnold installed is must have requirement to make this process work smoothly.

The export code could certainly use some error checking as to what plugins are required to be installed/loaded. Would be nice to have some sort of popup dialog letting the user that you’re missing some required elements before generating the scene. Otherwise the user is left with an unusable scene.

hbkcracker · April 25, 2021, 11:59pm

Hello, I don’t understand why we need to install another Arnold. Isn’t maya2020 with Arnold?

hbkcracker · April 26, 2021, 4:01am

Hello, I don’t understand why we need to install another Arnold. Isn’t maya2020 with Arnold?

anonymous_user_982cfb951 · April 26, 2021, 10:35am

Maya LT version comes without Arnold. In that case Arnold needs to be installed. This is just a temporary workaround until we remove all Arnold dependencies used in common assets.

DragonSlayer981 · April 26, 2021, 12:47pm

Hi, I downloaded Arnold from the Autodesk website. I get the folder “Arnold-6.0.0.0_SDK_Windows”, not sure how to actually get it onto Maya though?

hbkcracker · April 26, 2021, 1:37pm

Thank you very much for your reply, but we already have Arnold’s. how can we solve this problem

weijianghao · April 28, 2021, 2:58am

* You can see that Face_rig is not included in the downloaded file

SE_JonF · April 28, 2021, 6:29am

Yeah I can’t get the face whenever I open up the Maya scene that comes with the source download. It makes it impossible for me to use MetaHuman unless I pay for the full version of Maya and use the export feature.
