You can natively import .c4d files directly into Unreal Engine with support for scene hierarchies, geometry, materials, lights, cameras, and baked animations. ‘Save for Cineware’ command will let you bake complex procedural motion graphics directly into real-time scenes through the Unreal Engine Sequencer cinematic editor.
“We are thrilled Epic Games is introducing native support for Cinema 4D in the latest release of Unreal Engine,” noted David McGavran, CEO, Maxon. “The new Datasmith plugin promises to deliver a more seamless content creation experience and creative flexibility to meet the demands of real-time, high-quality, interactive content creation.”
“Support for Cinema 4D in-engine adds an important dimension to Unreal Engine viability for content creators across motion graphics and animation,” said Andy Blondin, Technical Product Manager, Mixed Media, Epic Games. “The active Cinema 4D user base, particularly in broadcast and motion graphics, has been asking for direct hooks from Cinema 4D into engine. Even though this feature is just now available in our 4.23 preview, the user base has already taken advantage of real-time workflows to deliver really impressive results.”
