Cinema 4D Release 10

Cinema 4D 10 is one of the heavyweight professional 3D packages, but it's also surprisingly simple.
This latest release boasts a spruced-up interface, with new icons and workspaces, as well as a new browser-based help system.

Expanded OpenGL support also now provides more realistic visual feedback including real-time reflections, bumps and hard shadows,
although it still can't compare with the final rendered results.
This is where version 10's new Interactive Render Region capability comes in, allowing you to mark up your viewport, or a section of it,
to be automatically rendered as soon as you pause working.
