FBX, or Filmbox, is a popular file format used for 3D modeling and animation. Developed by Autodesk, it allows for the exchange of 3D assets between different software applications, making it easier for artists and developers to collaborate. FBX supports a variety of features, including geometry, textures, lighting, and animations, which are essential for creating realistic 3D environments. The FBX format is widely used in industries such as gaming, film, and virtual reality. Many software programs, including Maya, 3ds Max, and Unity, support FBX, enabling users to import and export 3D models seamlessly. This versatility makes FBX a key tool in the digital content creation pipeline.
