Unity acquires Ziva Dynamics, creator of hyper – realistic digital humans powered by machine learning

The developer of ‘software’ for videogames Unity has acquired Ziva Dyamics, a company specialized in the development and creation of hyper-realistic virtual characters with machine learning through the simulation technology.

With the purchase of Ziva, Unity intends to democratize the tools of creation of virtual characters on different platforms, with the aim of offering greater possibilities to visual artists and that they can use their technology for their creations.

“Create digital human beings that meet the quality and natural dynamics necessary to truly satisfy our minds it can be a complicated and painful endeavor, requiring both expert knowledge and extreme perseverance. Ziva Dynamics is solving that problem,” Unity senior vice president and general manager Marc Whitteman said in a statement.

Ziva is Unity’s latest acquisition, following its purchase of Peter Jackson-founded special effects studio Weta Digital; 3D development software SpeedTree; as well as SyncSketch, Pixyz Y Subtract.

The company has also expressed its intention to accelerate the process to bring the tools of another of its companies, Weta Digital, to the 3D technology through the cloud in real time and with the power of Ziva’s machine learning.

One of the characters created by Ziva Dynamics is Emma. This hyper-realistic digital human has exposed how it works and what are the goals that Unity intends to achieve in the near future with the technology it has just acquired.

“I am driven by state-of-the-art biomechanical simulation and I work in real time in Unity,” says Emma, ​​which is powered by machine learning. This model was trained with more than 30TB of data 4D unique using a facial training system, ZRT Trainer.

Thanks to this one, Emma you can get excited showing more than 72,000 gestures and can achieve completely new facial expressions. In addition, the image received from these robots depends on the lighting conditions, so they adapt to them to generate a more realistic sensation.

This hyper-realistic technology is not only possible on human-like characters, but is designed to power any element or be capable of being digitized in high quality: from humans to creatures, animals or clothes.


For the creation and development of her virtual characters, Ziva uses the Ziva VFX ‘software’ to digitally replicate and couple the materiality of human soft tissues, such as muscle, fat or skin.

This technology is based on advanced engineering practices and biomechanics, whose combination results in total autonomy and great dynamism of the CGI characters (abbreviations in English of image generated by computer).

Ziva simulation data can be used to train creatures and characters to interact in different environments in real time using ZivaRT. This system allows us to reconstruct with great detail and precision the behavior of the non-linear facial deformations of the characters.

It should be remembered that Ziva’s work has been taken to the cinema on previous occasions, such as the film Godzilla vs. King Kong and TV series like Game of Thrones. In addition, its results have also been included in video games, such as Senua’s Saga: Hellblade II, by Ninja Theory.
