iClone vs K-3D

iClone is a Windows application for character rigging and real-time capture, including facial tracking. It supports Windows 10 and Windows 11 and exports FBX, OBJ, ABC, and USD files. The listed capabilities do not include 2D animation, 3D modeling, motion graphics, or cloud collaboration. iClone uses a freemium model with a Free Personal Edition priced at free, with no time limit and 30 3D exports. The iClone 365 and iClone 8 plans each list 2,000+ free assets, but their prices are not provided. Capture sources are both, and the product is intended for users working with rigged characters and captured motion on Windows. The maker is headquartered in Hsintien, New Taipei City, Taiwan, and was founded in 1993.

K-3D is free desktop software for 3D modeling and animation on Linux, macOS, and Windows. It supports procedural and parametric workflows, with interactive property changes and immediate results. A node-based visualization pipeline connects components and passes selections between modifiers. An undo tree supports both undo and redo operations. The site describes native RenderMan support within the K-3D interface, plus real-time mirroring and welding of one side of a model into a subdivision surface.
