Smarter AI perception for any AI.

The APS Visualizer

See what your AI is thinking

Tick Show Visualizer on any AI and it draws what it sees, hears and believes, live in your game.

  • View cones that stop where its sight stops
  • The points of you it can actually see
  • Every sound it heard, and how loud it arrived
  • A live panel: its belief in you, sense by sense

Blueprint first

A working guard in five nodes

When it detects you, it comes for you. When it loses you, it goes where it last saw you. APS does the seeing, hearing and remembering.

Any AI

Not just guards

Everything an AI perceives is set on its Perception Profile. A guard, a sniffer drone, a security camera or a blind monster is a different profile, not new code.

Why APS

APS and Unreal's own AI Perception

You can run both: APS doesn't switch Unreal's AI Perception off, so you can move over one AI at a time.
