Overview

What the Animatica for MotionBuilder plugin is and what it does inside your scene.

Animatica for MotionBuilder is a dockable tool window that brings AI motion generation into your MotionBuilder scene. You describe the motion you want in plain language ("a person walks forward, then waves"), and the tool sends that request to an MMCP (Motion MCP) server — either a local server on your machine or Animatica Cloud — and applies the returned animation to a skeleton in your scene.

Beyond text-to-motion, the tool lets you:

  • Import existing motion from .npz, .bvh, .glb, or .gltf files.
  • Steer the AI with spatial constraints — pin a full-body pose, place hands or feet at exact positions, or draw a path the character should follow.
  • Sequence multiple prompts on a visual Prompt Timeline, so a character performs a series of actions back-to-back — and because every skeleton keeps its own set of prompt boxes, you can author separate performances for multiple characters in the same scene.
  • Generate a single pose at the current frame.
  • Route the result into a new take, an existing take, or a MotionBuilder Story track, and optionally bake it onto an HIK Control Rig for hand editing.

The tool is skeleton-agnostic: it ships with a canonical humanoid layout, but if you point it at your own rig, retargeting happens on the server and the motion comes back on your skeleton.

Concept in one line — Describe motion → the MMCP server generates it → the tool applies it to a skeleton in your scene. Everything else in the window is about which skeleton, how the motion is steered, and where the result lands.
