A ZRT file is the resulting file type that you export after training your character in Ziva Real-Time Trainer. The Trainer processes all of your character’s data from its Alembic, FBX, and map files (typically several gigabytes of data) and encodes it as a small ZRT file (as small as 20 MB).
You can import the ZRT file into an application that integrates the Ziva Real-Time Player and drive the character’s deformation. Supported applications include Maya, Unity, and Unreal, or a proprietary RT3D environment via the source code software development kit (SDK). Connect with us for more on the SDK.
