UE4 A.R.T. Tool Error with deformation setup

Nodixal · April 1, 2016, 6:11pm

Hi there,

I’m using the A.R.T. tool on Maya 2014 x64. When I try to go to the deformation tab, I get this error when skinning the proxy mesh.

Traceback (most recent call last):
File “C:/Users/Julien/Documents/maya/2014-x64/scripts/MayaTools/General/Scripts\ART_skeletonBuilder_UI.py”, line 6981, in skinProxyGeo_UI_Accept
cmds.select("skin_geo_")
ValueError: No object matches name: skin_geo_
.
Aborting Operation.

If i click no to skinning the proxy mesh, I get this error instead

Traceback (most recent call last):
File “C:/Users/Julien/Documents/maya/2014-x64/scripts/MayaTools/General/Scripts\ART_skeletonBuilder_UI.py”, line 7004, in skinProxyGeo_UI_Cancel

.
Aborting Operation. Please correct naming conflict and try again.

Any idea?

I forgot to mention that I do not have a model imported in the scene yet. So it can’t be the vertex with no skin weight on them issue.

Hi Nodixal,

I was unable to reproduce this issue in Maya 2014 using the userSetup file from UE4.11 install directory. Please provide the following information and repro steps:

What version of the Engine did you copy the “userSetup” from?
Do you get this error with the default skeleton settings or you with own, custom skeleton
Can you reproduce this issue with the skeleton on the default settings

Thanks,

.

*Note: researching similar issues on the Maya point to this error being derived by a bad naming convention, so if you are creating a custom character/rig, make sure you have no spaces or special characters when you name bones, etc.

Hi Nodixal,

Since we have not heard back from you in a few days, we are closing this post for tracking purposes. If you are still getting an error when skinning the proxy mesh with the A.R.T., please respond with the requested information above and we will continue to try and help you resolve this issue.

I am getting this same error but I am using Maya 2016, here are the answers to your repro steps…

1 - I downloaded engine version 4.12.5. I could not find the userSetup.py file in the location specified here " ". There was no folder in the “Extras” folder names , so I downloaded everything including the userSetup.py file from the dropbox link in this forum. Animation and Rigging Tools: FAQ, Known Issues and Feature Roadmap. Once I downloaded all of that I installed it like the instructions say to. Everything worked until I tried to run the deformation set up, at which I got this error…

Traceback (most recent call last):
File “”, line 6981, in skinProxyGeo_UI_Accept
cmds.select("skin_geo_")
ValueError: No object matches name: skin_geo_
.
Aborting Operation.

2 - I got this error with the default skeleton, no custom anything, all default values. I also get this same error with any custom values I enter.

3 - Yes, the default skeleton is where this happened \

Let me know if I’m doing something wrong, thank you for your help!

I find that there are fewer instances of errors with the A.R.Tool, when you use consistent files from the same Engine version etc. To that end, please check that you downloaded the required tools correctly by clicking the down arrow by the Installed Engine version and selecting options as shown:

Make sure all boxes are checked as shown #1 in the image below. If so, go back and select “Verify” from the image above. The download should result in the userSetup.py file being installed in the location as shown #2:

If following these instructions do not result in the userSetup.py file being installed, respond and we will continue to troubleshoot. Also, if you have not already, please post this question on the Forum link where you download the files from.

Thanks,

.

Thanks for your reply -
The only thing I didn’t download was the editor symbols for debugging, I downloaded that, here’s a picture to verify…

I then browse to the extras folder and unfortunately there still isn’t a folder, this is what I see…

anonymous_user_bcdd396d · August 11, 2016, 8:47pm

It looks like you are missing three folders from this directory. Please click the “Verify” button pictured above and let me know if these directories do not populate:

MayaVelocityGridExporter
3dsMaxScripts

Looking at the Forum, the download has the message: *NOTE: The above link does not contain the complete toolkit. It only has the latest scripts and icons. Please copy the contents to the original install location on your machine!

I recommend backing up your Unreal Projects folder, deleting UE4.12.5, and reinstalling to make sure you have all contents of that folder.

anonymous_user_418b7ecb · August 11, 2016, 9:08pm

No dice, those folders did not populate after running the verification.

anonymous_user_418b7ecb · August 11, 2016, 10:30pm

So I uninstalled and deleted everything, then reinstalled. Those folders didn’t get created unfortunately. The weird thing is I had a friend download the everything the same way I did and those folders showed up with all the files. We installed the ART in his Maya and it works no problem. I’m going to copy the missing folders into my directory and try that. Thank you for your help, its much appreciated.
