I believe that Maya comes with UE4 for free. Or, at best, the link below is misleading. Assuming is it free, I cannot seem to figure out how to make the program work. I do have .py files in …\extras\maya_animationRiggingTools\MayaTools. I do not have any type of executable file, nor do I have the folder in my docs\maya that I have read about.
I have been researching into this for a while and must be missing something major. All I want to do (assuming Maya is free) is install it and start using the software. I am an active registered member to UE4.
I might be wrong but I think that this is addon/plugin for Maya. Maya itself costs quite a bit but you can get it if you say your a student. I would also recommend that you check out 3ds max. I have only used blender (which is free and greate if you are a beginner. You can get an addon so it can export files for UE4) but I have heard both programs by Autodesk are good.
Hope this helps!
Heres the link to a guy that makes great tutorials. Their a bit hard to follow at first but the blender community is amazing. Just to start learning the UI I suggest the second link.
