Earns its place for pairing an in-viewport character browser with placement tools like Fill Curve, formations, and Auto-Walk, so crowds come together without leaving Blender.
Animated Background People is a Blender add-on that populates scenes with animated FBX characters and crowds. Its library holds 80 characters — 40 men and 40 women — each with 8 different animations, in 7k and 800-tris versions. It is compatible with Mixamo and Character Creator exports and basically any FBX rig.
A thumbnail grid browser lives in the N-panel with pagination, search, and filters for gender, animation type, theme, and resolution. One-click import drops characters at the 3D cursor, or Place mode lets you click anywhere in the viewport. Fill Curve populates a drawn curve with random or chosen characters using live spacing and rotation controls, formations like Stadium Crowd and Talking Group place whole groups at once, and Look At makes heads track any object. Auto-Walk moves characters forward or along a path with adjustable speed, and all animations loop automatically on import.
Texture sharing aids performance and render times, and a custom library folder is supported. The add-on is actively developed with free updates, and expansion packs are planned. It is built for archviz, film, and game artists who need crowds, audiences, and background life.
Animated Background People is best for archviz, film, and game artists who need crowds, audiences, and background life in Blender scenes.
Animated Background People is completely free to download and use.
Animated Background People supports Blender versions 4.0 through 5.0 and is listed as Blender Extension compatible. It installs as an add-on and adds a thumbnail browser to the N-panel, so you browse, filter, and place characters directly in the viewport. The characters are animated FBX rigs, and it is compatible with Mixamo and Character Creator exports as well as basically any FBX rig. If you run a Blender version in that range, the placement and browsing tools are available inside the viewport.
Animated Background People supports a custom library folder alongside the main library, so you can add your own animated character library. It is compatible with Mixamo, Character Creator exports, and basically any FBX rig. The Look At feature, which makes heads track an object in the scene, also works with most custom characters. Animation retargeting lets you swap an animation by clicking another character, and Auto-Walk can move characters forward or along a path with adjustable speed.
Animated Background People includes 80 different characters, split into 40 men and 40 women, and each character comes with 8 different animations. Every character ships in a 7k version and an 800-tris version, so you can balance detail against scene weight. All animations loop automatically on import, and texture sharing is used for better performance and fast render times. Expansion packs are planned, adding themes like Zombies, Beach people, Business people, Gym people, Wild West, Medieval, and Sci-fi.
Animated Background People is listed as free in this catalog. Licensing and any current pricing can change, so check the developer's page for the latest terms before you download. The add-on is distributed under the GPL license.
