The fxl file extension is associated with FaceFX. FaceFX creates realistic facial animation from audio files. Fxl stands for FaceFX Language file. Facial expressions are stored in an facial expression library file. These files store primitive and compound expressions. Different models can affect how expressions appear. When a model is loaded, an expression library file is often auto-loaded for it. FXL files store facial expressions for a character model. The file to load for a character is specified in the .CHRPARAMS file. Multiple free online apps can view, edit, convert FXL files without installing anything. Programs that open FXL files include Crytek CryENGINE. FXL files save instructions that could be manually entered at the FaceFX command line.
FXL files store facial expressions for game character models. The file defines facial expressions like anger and smiles. Each character defines a different FXL file. The CHARPARAMS file defines what FXL file to load per character. FaceFX software can open FXL files. If the operating system cannot open FXL files, the software to open it is not installed. Downloading an application with FXL support allows viewing, editing and saving FXL files.
