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"

OSX Art Tool Ships with Compiled Python Files

The current version of the Art Tool for Maya ships with compiled python files that contain tokens to Windows paths. This breaks UI methods in the "Add Character" dialog. (As well as other items I haven't tested yet).

EXPECTED: Since Python will automatically recompile these the first time they are run on the system, all Python compiled files (.pyc) should be removed before shipping. ADDITIONALLY: There is a Python Windows DLL file in the form of .pyd that COULD potentiality cause issues. (I don't know what it's being used for or if the libraries ˙ave been migrated to OSX. But this could be a secondary bug with file: P4API.pyd


  1. Install tools on OSX

  2. Select "Add Character for Animation" from Epic menu...
    RESULT: "Add Character" box opens.

  3. Select "Add" from the "Add Character" (Animation & Rigging Tools window....

RESULT: Error dialog pops up indicating a Windows path:

"Reference file not found D:/Build/UE4-Releases/4.0/Engine/Extras/Maya_AnimationRiggingTools/MayaTools/ART/Projects/Sample/ExportFiles/Mannequin_Export.mb"


Going into the following path and deleting ALL .pyc files fixes this and other errors resulting from the windows tokens.

Hi Nina,

The Mac port of ART is not an official one. It's creator (alexwidener) may be able to help you. His thread about it can be found here: https://forums.unrealengine.com/showthread.php?62654-ART-Toolkit-Ported-to-OSX
