FBX is a file format from Autodesk that allows users to move their geometry from one program to another with minimal effort. It is exportable from Autodesk Maya and 3DS Max, and works with Unreal Engine and Unity out of the box without the need for additional conversion. Autodesk provides multiple ways to use the format, including a free viewing application that is easy and intuitive to use for previewing models. Review collected by and hosted on G2.com.
While FBX is able to allow models to travel across different programs, it does come with some significant limitations. Some distortion may occur if geometry is not cleaned effectively. Smoothing will not be uniform if not "baked" into the model, making it a non-editable format. Maps will also have to be reapplied within the application and saved to a new file within that software's ecosystem, taking longer at times than importing the native file directly if it is supported by the engine. Occasionally, certain opacity properties will cause odd effects when viewing a model in a different software than the one originally intended, causing more time to occasionally be needed when transferring from one program to another.
