Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Maya Animation and Rigging Toolset| cannot bind skin

Hi,

Thanks for making the toolset. It looks great but im unable to bind my own mesh to the skeleton.

At the deformation setup phase I am trying to smooth bind my mesh to the skeleton. All attempts have failed so in this case, I am using a sphere for a simple test. I've used all the default A.R.T. settings on my way to the deformation setup part and I am selecting my sphere (pSphere1) and ctrl+lmb "root" skeleton node. when i click smooth bind i get the error:

SmoothBindSkin; performSkinCluster false; // Error: line 0: Problems occurred with dependency graph setup. //

If i then try to go back to Skeleton Placement, I get the error:

Error: TypeError: file C:/Program Files/Unreal Engine/4.0/Engine/Extras/Maya_AnimationRiggingTools/MayaTools/General/Scripts\ART_skeletonBuilder_UI.py line 21299: 'NoneType' object is not iterable #

At some point I also came across this error so I'm leaving it here in case it's helpful:

// Warning: Panel size cannot accommodate all requested Heads Up Display elements. // # Warning: 'spine1_shapes.spine_1_bust' is already connected to 'spine2_shapes.spine_2_bust'. # UI Refreshed # Error: RuntimeError: file C:/Program Files/Unreal Engine/4.0/Engine/Extras/Maya_AnimationRiggingTools/MayaTools/General/Scripts\ART_skeletonBuilder_UI.py line 17425: Problems occurred with dependency graph setup. #

Thank you for any help.

Ah,okay.This issue just isn't properly documented.So,you first need to 'publish rig' (just make it look as close to your custom model as you can;I also kept my own mesh inside this file,just in case),and after that,once it's 'published' (make sure you specify a new name for the project and for the character),I clicked edit rig button,and then you can smooth bind your mesh to the newly published rig...

So that worked an all and let me bind the mesh, but now when trying to re-"build" or publish the rig I get this error: # Error: RuntimeError: file C:/Program Files/Unreal Engine/4.0/Engine/Extras/Maya_AnimationRiggingTools/MayaTools/General/Scripts\ART_skeletonBuilder_UI.py line 14563: setAttr: The attribute 'root.rotateX' is locked or connected and cannot be modified. #

Anybody have an idea on what could cause/fix that? This error is happening in Student version of 2013, and its in both cases of trying to build as a new Character and trying to build as the pre-existing character.

Hi all

I have found a work around that you can do before completing the rig:

On the step where you would attach your model run the following command in MEL script:

 string $gffu[] = `ls -sl`;
 for ($rfo in $gffu) 
 {
  lockNode -lock off $rfo;
 }

This will unlock the nodes for binding to the mesh. This will allow you to use your own mesh and do the weight painting as described in the rest of the tutorial !

If you run into any problems let me know.

(P.S. I do not work for Unreal - this is not an official fix)

Hm, that is indeed a bug then. What seems to be happening, is I lock down the skeleton after the deformation setup phase, but it doesn't get unlocked until the publish phase, which is incorrect. I will fix this as soon as possible and get the files on github updated. I'll also post dropbox links in this thread for immediate download as well. Thanks for finding that workaround Michiyuki13!

I have the same problem:

I have a my own model mesh and the rig that was created with the UE4 A.R.T. toolset in Maya that I need to bind together, however when I try and smooth bind these in Maya 2014 I get the following error:

Error: line 0: Problems occurred with dependency graph setup.

Anyone know what I can do to fix this ?

see if Michiyuki13's workaround will work for you. I'll be updating the code within the next 24 hours.

As for any other errors, just paste the error messages you get and the maya version you are using and I'll do my best to get them fixed as soon as possible!

Hi Jeremy, Where on GitHub can I find ART, I can't seem to find it at EpicGames?

avatar image SwitchNZ Mar 26 '14 at 10:19 AM

It's in the source under Engine\Extras\Maya_AnimationRiggingTools

avatar image mgf Mar 26 '14 at 10:20 AM

hi Jeremy,

woohoo! thanks for looking into this. I'll check Michiyuki13's workaround when I get home. I think I remember doing something similar and having it work.

kfredberg: if you're asking about the original a.r.t. script, you can find it under program files/unreal/engine/extras/Maya_animationriggingtools. I can't check the exact path at the moment but its in there

this is a long shot but I might as well ask while I'm In here, any chance anyone knows a tutorial/resource for exporting set driven keys? it'd be great to have them working on my rig in ue4.

thanks!

avatar image KFredberg Mar 26 '14 at 12:29 PM

thanks, but I was looking for the repository on GitHub that Jeremy refered to.

avatar image SwitchNZ Mar 26 '14 at 07:53 PM

Oh sorry, I see what you mean....

Yep seems the only way to get it is through the releases page on GitHub rather than being visible in the navigable sections of the GitHub repository

Link in case you don't have it (not trying to be patronising):

https://github.com/EpicGames/UnrealEngine/releases

The source code zip contains these extras.

EDIT: I have now logged a feedback request to get these files on the main repo.
