Animate 3D

Bring your 3D design to life: turn it into an animated model for your game, with a skeleton and animations, free and in your browser. Or say how you want it to move and get a video for your website or social media.

Animated model for games

  • Open your design: a character, an animal, a figure or an object, as GLB, STL, 3MF or OBJ, or a model from your projects. You choose its height in the game and the detail: 10,000, 30,000 or 60,000 triangles.
  • The skeleton is added automatically and fits the shape, with the bone names game engines expect; you can move its joints. A figure on its base moves its head and tail; an object moves as a whole.
  • Choose the animations (walk, run, jump, wave, dance…) and watch them live, for free. Save it in My projects; with Pro, Max or Business you download it as GLB and FBX for Unity, Unreal, Godot or Blender.
  • The skeletons and animations are public domain (CC0, from Mesh2Motion and Quaternius): use them in your game, even if you sell it.

How it works

  • Choose the design: a model from your projects, a GLB, STL, 3MF or OBJ you open in the viewer (you turn it to the starting point of view) or an image. From an image, its 3D model is made too.
  • Say how to animate it: write it in your own words or start from an example. You choose 5 or 10 seconds, the quality and the format: landscape or portrait for Reels, TikTok and Shorts.
  • Check the cost and animate: you see the exact cost before confirming and, if it fails, the credits come back. The video stays in My projects; with Pro or Max you download it as MP4.

How it looks

  • Showcase: “It slowly turns on its base, like in a shop window, under soft studio light.”
  • Happy: “It wags its tail, tilts its head and sticks out its tongue, happily.”
  • Wings in the wind: “The dragon slowly flaps its wings and looks at the camera.”

Good to know

The video is your design in motion: the AI moves what it sees in the starting frame and may change a detail. Review the video before you publish it.

The video comes with sound; in the player it starts muted. Anyone can watch it; downloading it as MP4 comes with Pro or Max.
