Firstly, you will need to register for an account with Ziva (it’s free!). Here you can access Ziva Face Trainer. Then, you can use any 3D Software such as Maya, Houdini, and 3ds Max to create a face mesh, as long as that software creates polygons and can be converted into an FBX file. This can then be run through Face Trainer after undergoing the Face Preparation stage (using these instructions).
