Ziva Dynamics has introduced Ziva VFX 1.7, designed to make CG character creation easier thanks to the introduction of Art Directable Rest Shapes (ADRS). This tool allows artists to make characters conform to any shape without losing its dynamic properties, opening up a faster path to cartoons and digi-doubles.
Users can now adjust a character’s silhouette with simple sculpting tools. Once the goal shape is established, Ziva VFX can morph to match it, maintaining all of the dynamics embedded before the change. Whether unnatural or precise, ADRS works with any shape, removing the difficulty of both complex setups and time-intensive corrective work.
The Art Directable Rest Shapes feature has been in development for over a year and was created in collaboration with several major VFX and feature animation studios. According to Ziva, while outputs and art styles differed, each group essentially requested the same thing: extreme accuracy and more control without compromising the dynamics that sell a final shot.
For feature animation characters not based on humans or nature, ADRS can rapidly alter and exaggerate key characteristics, allowing artists to be expressive and creative without losing the power of secondary physics. For live-action films, where the use of digi-doubles and other photorealistic characters is growing, ADRS can minimize the setup process when teams want to quickly tweak a silhouette or make muscles fire in multiple ways during a shot.
According to Josh diCarlo, head of rigging at Sony Pictures Imageworks, “Our creature team is really looking forward to the potential of Art Directable Rest Shapes to augment our facial and shot-work pipelines by adding quality while reducing effort. Ziva VFX 1.7 holds the potential to shave weeks of work off of both processes while simultaneously increasing the quality of the end results.”
To use Art Directable Rest Shapes, artists must duplicate a tissue mesh, sculpt their new shape onto the duplicate and add the new geometry as a Rest Shape over select frames. This process will intuitively morph the character, creating a smooth, novel deformation that adheres to any artistic direction a creative team can think up. On top of ADRS, Ziva VFX 1.7 will also include a new zRBFWarp feature, which can warp NURBS surfaces, curves and meshes.

According to Michael Smit, chief commercial officer at Ziva Dynamics, “Ziva is working towards a new platform that will more easily allow us to deploy the software into other software packages, operating systems, and different network architectures. As an example we are currently working on our integrations into iOS and Unreal, both of which have already been used in limited release for production settings. We’re hopeful that once we launch the new platform commercially there will be an opportunity to deploy tools for macOS users.”
