Autodesk Maya is a very comprehensive 3D formatting program. That includes modeling, texturing, highlighting, animating and rendering. If the extensiveness of the functions or their strenght is not enough, it is possible to install many plugins that supplement Maya. These add-ons range from the simplest groups of scripts, to complex interfaces with which anything can be done. This thesis describes the features and operations of some of the more popular accessories, some of which are used in the film and gaming industry for their strength. At the beginning, the Autodesk Maya program is briefly described. The plugins that the thesis deals with are then listed. Some plugins also provide a step-by-step workflow, as well as an example of the results that can be achieved. Finally, plugins that serve a similar purpose are compared.
