This version adds the Spline IK Component to the Hive Auto-Rigger which dramatically upgrades all of our default templates (Biped, Natalie, Zoo Mannequin). An Asset Pack upgrade is coming soon with upgraded demo rigs.
The new Spline Spine is a versatile hybrid IK/FK spine targeted at both realistic and toon rigs for bipeds and quadrapeds. The spine can also be modded and used for long necks and toon legs and more.
We’ve improved support for ACES Color Space in Maya 2023 for all color related tools, and added the new Match Swatch Color Space tool for upgrading swatch colors on old scenes and FBX models to newer scenes that use ACES colorspace.
Zoo 2.7.1 also includes many other enhancements and bug fixes.
Hive Auto-Rigger (Beta) – New Spline Spine Component
Hive Auto-Rigger now has a brand new Spline Spine component, the spine is a hybrid FK/IK spline spine and new templates with the Spline Spine added.
The new Spline Spine is useful in a wide variety of situations and its targeted at toon and realistic rigs, bipeds and quadraped spines. The component can be moded for other parts such as toon legs and long necks.
