Denis Kozlov has released a proof-of-concept video for a procedural system that creates, textures and animates creatures. It was created using Houdini consisting of about around 17000 nodes with CHOP-based generators as core modules for shapes.

Final meshing is VDB-based with intermediate steps that can involve polygons and or NURBS.

FEM simulation is used for animation enabling a “flexible marionette-like rigging”.
