Installing the Maya toolset
There are some useful scripts for exporting FBX files included in MightyBake. If you run the “Workflow -> Maya -> Install” menu item, MightyBake will search for any Maya installations and offer to install the MightyBake shelf in each of them. This shelf contains three scripts. Each script is used to export the low, envelope or high poly models. Using these scripts is the most reliable way of getting good results.
