Unity has released Ziva VFX 2.3, the latest version of its soft tissue simulation plugin for Maya. Apart from fixes in the detected issues, this version hosts a couple of noteworthy functionality as well.

Ziva VFX Release Notes Version 2.3

Functionality:

- Improved collision detection system.

The collision detection system is now more robust and efficient. Continuous Collision Detection has switched to using a swept motion intersection computation instead of a relative embedding approach. This leads to more accurate collision detection and fewer erroneous contacts.

Contacts in the new system are persistent. This means that contacts will be maintained between frames, even if the collision geometry moves, as long as the contact vertex is still touching the other tissue. Contacts will only be removed when the collision geometry moves away from the contact point in the proper direction.

Collision Subdivision checkbox.

Collision subdivision is now disabled by default. It needs to be turned on manually by setting the Collisions Subdivision attribute on the zSolver node to True. Additional collision points are now only added along the edges of collision triangles, instead of on their faces. Collision Subdivision data is pre-computed at the start of the sim. As a consequence, the Collisions Point Spacing attribute is not keyable anymore.

Initial penetration detection.

The simulation now performs an initial penetration test before running the first frame of simulation. Vertices found to be penetrating collision geometry will have contacts created for them as if they had previously come into contact with that geometry. This prevents small initial penetrations from being ignored by the Continuous Collision Detection system. Keep in mind that initial penetration detection creates contacts by finding the closest point on the collision geometry to the penetrating vertex. This means that very deep initial penetrations or vertices penetrating very thin tissues could result in erroneous initial contacts.

Maximum contact length.

A new Max Contact Length attribute in the zSolver node allows any penetration contact of more than the specified length to be removed from the simulation. Since contacts are now persistent, this tool allows users to remove potentially undesirable contacts from their simulation.

- A new Approximate mode of Curvature stiffness feature is added for better performance. The existing one is rename to Original mode. Check the Curvature Stiffness Mode attribute in the zTissue node for detailed information.

- Contact Line Width attributes is added to zSolver node. The contacts are more noticable by adjusting the line width.

Bug Fixes:

- VFXACT-1928 Contacts do not render when a tissue is selected in a tissue-bone collision..

Ziva VFXis the world's leading character simulation solution. The technology features a robust physics solver that enables artists to replicate the materiality and physics of any soft tissue object, including muscles, fat, and skin. This feature, along with the comprehensive collection of out-of-the-box rigging tools, has powered leading CG creatures in titles such as Captain Marvel, Aqua Man, Hellboy, A Dog's Way Home, Small Foot, and more. Ziva simulation technology, which leverage Intel's Math Kernel Libraries, accurately solves the relationship between organic soft-tissue (i.e., muscles, fat, and skin) and external objects such as fabric, textiles, metals, and foams. With simulated human models and digitally reconstructed retail designs, companies can effectively identify how products interact and influence the human body, reducing the demand for live fit tests and redundant manufacturing cycles.

What is Ziva VFX?

A brief introduction to Ziva VFX, the industry's foremost soft-tissue simulation software. The robust physics solver enables the most life-like dynamics of any simulation tool on the market, earning it the title of "Hollywood's most innovative technology" and helping lead numerous VFX studios to Academy Award wins.

Founded in early 2015 by Academy Award-winner James Jacobs and USC Professor/TR35-winner Dr. Jernej Barbic,Ziva Dynamicsis changing the way virtual characters are brought to life. Ziva fundamentally changes the character creation process, while providing greater control, speed, and capabilities to artists of all levels. Emerging artists, award-winning studios, and global brands are all leveraging Ziva's technology to make world-class characters for movies, TV, retail experiences, and interactive environments.Unity has announced it'd acquired Ziva Dynamics,  leader in sophisticated simulation and deformation, machine learning, and real-time character creation.
