What is a .FXA file?
The .FXA file extension is associated with OC3 Entertainment's FaceFX software, which is used to create 3D facial animations. These files are specifically generated by older versions of FaceFX, ranging from FaceFX 1.0 to 1.7.x. The .FXA files contain important data for animating 3D models' facial expressions, including the positions of facial bones, face graph nodes and links, and animation keys. This type of file is particularly useful in the development of video games, where it helps bring virtual characters to life by animating their facial expressions based on audio inputs.
To open and work with .FXA files, you can use the FaceFX software from OC3 Entertainment. Additionally, if you are using popular 3D animation software like Autodesk 3ds Max, Autodesk Maya, or Autodesk MotionBuilder, you can handle .FXA files by installing the FaceFX plugin. This plugin integrates with these programs, allowing you to manipulate the facial animations within a familiar environment.
It's important to note that .FXA files focus solely on storing animation data and do not include any specific project data from FaceFX. This design choice makes .FXA files relatively lightweight, which is advantageous for game development as it ensures that the animations do not excessively consume system resources during gameplay.
.FXA files have been largely phased out since the release of FaceFX 2009, which introduced the .FACEFX file format. However, they remain relevant for projects developed with earlier versions of the software. Some well-known video games that have utilized FaceFX animations include StarCraft II: Wings of Liberty, Mass Effect 2, and Assassin's Creed 2. If you're working with or encountering .FXA files, using the aforementioned software and plugins will be essential for accessing and editing the content effectively.
