In their own words
Houdini
Houdini is SideFX’s procedural 3D creation system for film, television, games, motion graphics, virtual reality and synthetic-data work. Its workflow stores actions in nodes connected as networks, and supports sharing workflows and custom digital assets with colleagues. Tools cover modeling, sculpting, animation, parametric modeling, character rigging, rendering and 3D-print export. Houdini FX adds simulation tools for fluids, destruction, pyro effects, grains and cloth. KineFX supports character rigging and animation, alongside tools for hair, fur, feathers, muscles and cloth. Karma renders images in the Solaris look-development workflow, while PDG distributes tasks, handles dependencies and creates datasets for machine-learning and AI applications. Houdini runs on Windows, macOS and Linux. The free Apprentice version is for non-commercial learning and personal projects; its renders are capped at 1920x1080 and carry a watermark. SideFX lists perpetual licenses, annual upgrades, rentals, subscriptions and education licenses. Listed paid pricing starts at $299/yr, though individual options have different terms and prices.
Spine
Spine is a 2D animation tool focused on making animations for games, with an editor and runtimes for using the results in games. It builds skeletal or cutout animation by attaching images to bones and animating those bones. Rigging and animation tools include inverse kinematics, paths, skins, meshes, free-form deformation, weights, a dopesheet, a graph editor, and runtime preview. Exports include JSON and binary animation data, animated GIFs, PNG or JPEG image sequences, AVI or QuickTime video, and texture atlases or spritesheets. Official runtimes support Unity, Unreal Engine, Godot, iOS, Android, Flutter, Phaser, PixiJS, and libgdx; generic runtimes are also listed for C, C++, C#, Haxe, and TypeScript. Spine runs on Windows, macOS, and Linux. Its free trial includes Professional features but cannot save projects, pack textures, or export animation data, images, or video. Essential is listed at $99 a month; Professional is $449 a month.
