Runway updates GenModel to produce UI motion capture and skeletal micro-interactions

AI · 4 min read

Runway's GenModel received an update that lets designers generate motion data formatted for UI and character micro-interactions, including velocity, easing profiles, and skeleton-like constraints for complex components. The generated motion can be exported as JSON or directly into Framer and After Effects-compatible formats.

The model was trained on a corpus of motion-design patterns and biomechanically plausible transitions to produce animations that feel natural across devices and contexts. Designers can specify intent—e.g., 'playful bounce' or 'professional slide'—and the model returns multiple variants with measured performance trade-offs.

Runway highlights potential uses across product and game UI: subtle character reactions, touch interactions that adhere to realistic momentum, and micro-entrances that maintain perceived performance. The company positions this as a tool to unify motion direction across teams while generating assets that are ready for engineering pipelines.
