FBX

FBX (.fbx) is a model format designed for animated models. It supports both model rigging and animation, as well as the ability to store textures within the model file itself.

FBX is an acceptable supplementary format on The Models Resource. DAE is preferred to FBX due to its wider support and plain text format.

Limitations

Because FBX is a binary file format, flaws in the model such as texture paths cannot be manually corrected or easily diagnosed if the model fails to load.

Precautions

It is easy for a FBX model to have a large file size if extra data is included. FBX models can store one or more animations, as well as all of the textures used by the included scene. If the model is not meant to be animated and the textures are already packaged with the model externally, this will lead to a lot of wasted space. To prevent this from happening, users should pay attention to the export settings when using FBX.
