What is Alembic? Alembic is a standardized format for data exchange between 3D programs used for animation and visual effects. It enables you to escape the trap of only using a single 3D program. If you use Exocortex Crate you can easily exchange data between the products supported by Exocortex Crate and Houdini, Modo, Nuke, Cinema 4D, V-Ray, Arnold, RealFlow, Clarrise and Lightwave.
