Autodesk 3ds Max vs K-3D

Autodesk 3ds Max is Windows desktop software for 3D modeling and animation. It is aimed at 3D generalists, modelers, animators, and look development artists working on game development, film and television production, and design visualization. Modeling tools include Smart Extrude, high-quality Booleans, and ReForm retopology. CAT and Biped provide rigging and character-animation setups. A built-in renderer and Arnold integration support rendering, while 3D print export handles output for physical production. Integrated OpenUSD support is intended to improve collaboration. Scripting and plugins such as tyFlow, thinkingParticles, and ForestPack extend the application. Flow Retopology moves mesh operations to the cloud, and Flow Studio can launch inside 3ds Max to send footage-derived elements through USD. It runs on Microsoft Windows 10 and 11. A free 30-day trial is available; paid subscriptions are $255 a month, $2,010 a year, or $6,025 a year billed every three years.

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.

Downloads include macOS, Windows, and source code; development information also lists GNU/Linux, MacOS X, FreeBSD, Microsoft Windows, and other build platforms. Optional build integrations include Collada, DBus, GLX, Gnome VFS, GTS, ImageMagick, ODE, OpenCASCADE, and OpenEXR. Documentation is provided through an archived wiki, with forums, a development mailing list, and issue submission for support.
