Framestore has been producing award winning creature effects for over 20 years, with complex rigs and realistic animation being crucial elements of these creatures’ visual fidelity. The studio has a long history of building bespoke tools and technology. In this talk, we present FIRA, a machine learning based pipeline which allows for the extension of a largely proprietary stack of simulation and rigging tools into an emerging domain of realtime workflows. FIRA allows for fully simulated render resolution rigs to be used in previs and virtual production workflows and provides a portable, high performance representation of a VFX deformation rig that can easily be used in different DCCs and applications.
