The layers of a Ziva lion
Ziva Made Its own lion, called Zeke, to show OFF the Features of Its FEM solver
Bones to begin:
The underlying structure of the lion is a set of anatomically correct bones. Ultimately, having that as the base will impact on the simulation of the soft tissues in the layers above, allowing them to naturally flex, jiggle, collide and fold.
ZIVA VFX’S Attachment Painting tool enables artists to quickly attach the lion’s anatomical components and assign custom attributes. Zeke's muscle and bone groups then react accurately to the strain and constraints of neighbouring anatomy.
fat and tissue:
With those underlying structures solved, ZIVA VFX then facilitates secondary motion that follows the laws of physics. Varying levels of elasticity can be painted onto a single tissue, resulting in the non-linear wiggle and jiggle of fat under gravity and force.
Skin, hair and lighting solutions can be carried out with tools external to ZIVA, but since this is a Maya plugin, the workflow is intended to mimic what happens in a typical animation or VFX pipeline.
