Has an extensive list of tools for modelling, look development, rigging, animation, rendering and exporting.
Pro Combining powerful, realistic rendering with ease of use
Arnold is now the default interactive renderer, which can be found in the render settings. Solid Angle's global illumination ray tracer is used by many Hollywood studios.
Pro Industry standard
Maya has been the industry standard for 3d modelling and animation for years.
The MEL language allows one to either write custom scripts or to download them.
Extensive support from Autodesk and users around the world.
Don't expect to get Maya cheap. It is considerably more expensive than lesser 3D programs.
Con Difficult to learn
Expect to look at tons of tutorials.
Con Poorly organized interface
The menu organization doesn't make sense, and leaves you searching all over the place for functions that should fall under one category. For example, the option to bake your animation isn't under the Animation menu.
