ABSTRACT
We present techniques to smash render hair under hats and headsets in animated shots that produce significant savings in time and disk space. Techniques are discussed to smash both the fine render hairs and the Level of Detail (LOD) hairs where low resolution proxy tubes riding on guide curves are substituted for fine render hairs. Precise collision resolution is ensured for those tight fitting collision objects. This procedural hair smash technique was used in the feature films Turbo, Penguins of Madagascar, and HOME, and allowed the automated creation of a large number (hundreds) of hair variations with ease. These variations are stored in a library and are used to generate the smashed hair on individual characters in a shot at render time.
