CINEMA 4D or C4D is a 3-D application that is popular amongst matte painters in film production, largely due to the BodyPaint 3D functionality. It is equally popular amongst motion graphics artists, thanks to its excellent integration with compositing application pipelines, and a very artist-friendly, customizable workflow and interface. It has been used for films such as We Are the Strange, Polar Express, Open Season and Monster House. Four different packages have been released by MAXON: the core CINEMA 4D application, the XL-Bundle (including NET Render [3 licenses], PyroCluster, Advanced Render, MOCCA and Thinking Particles), the Studio Bundle, which includes all modules, and the Production Bundle, available only upon request, which comes with a service contract, Linux version, Renderman support and a number of other high-end studio-specific features.
