You can set the following preferences in the Modules category of the Preferences window.
To return to the default factory settings, choose in this window. Note that this resets the preferences in every category in the Preferences window.
Maya includes a number of different software modules. Each time you start Maya, the software loads all the available licensed modules.
Loading several modules can use a lot of RAM and thus increase the start-up time. To avoid this, you can disable one or more of the modules. You can still load a disabled module by selecting it from the main menu bar.
You can also disable various modules based on the specific tasks you are performing. For example, if you are only rendering, you can improve system response time by disabling Dynamics.
