Fabric Engine includes a set of character classes that help you to build high-level character tools. These classes make it easy to import characters from FBX or your own proprietary file format and render that data in Fabric using the new Splice Drawing system. Once Fabric has the data, you can populate your previz scenes with many background actors or run large crowd scenes in real-time.
