Maxon Cinema 4D Import-Export Pro is a Blender addon for moving .c4d projects between the two applications. It imports selected .c4d project files directly from Blender, with no need to keep Cinema 4D open, and it appears in Blender's file menu so you can open, edit, and re-save native .c4d projects. Geometry, materials, animations, cameras, lights, splines, hierarchy, and scale are preserved during transfer.
Transfer runs both ways: export Blender scenes back to .c4d from the same panel. Full-fidelity transfer covers meshes, materials and textures, UVs, bones, shape keys, lights, cameras, splines, and keyframes. Two conversion modes are on offer, Precision Mode for pixel-accurate assets and Fast Mode for faster iterations, switchable at any time, while smart scaling matches units automatically between the two DCCs.
The Pro feature set adds support for advanced Cinema 4D systems, including XPresso, MoGraph Cloner objects and instances, Effectors, Matrix Animation, Dynamics, and Fields. It runs on Windows, macOS, and Linux (cloud conversion beta) across Blender 3.6 LTS to 5.0+, with custom cache and logging, an optional header button, and English and Simplified Chinese localization.
