Abstract:
Realistic-looking digital humans in visual effects are a crucial aspect of creating a believable experience for the viewer. In order to create a convincing result, a lot of effort is put into the details. In this talk, we look specifically into the details of the human skin and how we implemented a fully procedural approach to generate and visualise skin textures. The tool is integrated into our VFX-pipeline as a SOP (surface operator) in Houdini and provides an artist-friendly interface with many ways to modify and tweak the output appearance. Additionally, we provide a way to utilise the underlying animation to produce pores and wrinkles dynamically driven by stretch and compression in the current frame.
