A Solid Product
Unlike other complex software C4D is amazingly solid. No freezes, lockups or other frustrating behavior. Even the demo software works without an install, just run the .exe directly.
For our current project we agonized over buying an upgrade to 3D Studio or learning a new program. Given the unreasonable cost for an upgrade, difficulty working with Autodesk, old fashioned interface and frequent lockups, the decision to go to Cinema 4D was easy. It does everything in an up-to-date interface, solid reliability and a pleasure to use package. The only issue so far is that models imported in other file formats (.3ds, .lwo, etc.) require a bit of rework to get them to work.
