IPROJECT File Format Details What It Stores This format stores iClone project scene data, including characters, props, cameras, lights, animation data, materials, and other scene elements used in an iClone project. Primary Use Cases Real-time cinematic previz for film and television. Character animation for indie game development. Rapid creation of social media and marketing content. Strengths Optimized for high-performance real-time playback. Streamlined integration with motion capture hardware. Keeps full iClone scenes reusable for later editing, rendering, and animation refinement. Limitations Proprietary format restricted to the Reallusion ecosystem. Large or complex iProject files can load slowly, fail to load, or crash if temporary disk space or system resources are insufficient. Common Software Support Primarily supported by Reallusion iClone. External workflows use supported export formats such as FBX, Alembic, OBJ, or USD/Omniverse workflows, depending on version, edition, and plug-in support, or dedicated bridge/live-link tools such as iClone Unreal Live Link. Additional Notes While iProject is a proprietary iClone project format, Reallusion provides Live Link and export workflows for moving characters, cameras, lights, props, and animation data into supported external pipelines.
