Highlighted Features

Moving NavMesh

Kythera AI makes it effortless to generate navigation meshes on moving geometry. Our library functions enable navigation meshes to merge, allowing for exciting gameplay moments such as boarding sequences between moving ships.

It supports all of our other ground navigation mesh features, such as dynamic regeneration, Navigation Links, Cover, and Material Markup.

Hierarchical Pathfinding

Perform pathfinding in massive, partially loaded worlds with a hierarchical structure, automatically generated as part of the standard navigation mesh generation workflow.

AI Planning

Kythera AI ships with a state-of-the-art AI Planning system. This is more expressive than the well-known Goal-Oriented Action Planner, enabling your NPCs to deliberate about their actions and environment.

Combined with Kythera AI's other features and tight integration with Unreal's AI system, such as behavior trees, developers can create much more intelligent NPCs and exciting gameplay.

NavMesh Extensions

Kythera AI provides support for multiple-sized agents on a single NavMesh out of the box. Our navigation mesh generation pipeline is built with flexibility in mind, allowing you to access, modify, and extend the navigation mesh capabilities.

For example, add additional data to the NavMesh to allow characters to conform to their wading depth constraints when moving through water, build influence maps, or create agents that avoid well-lit areas to better hide from players. Let your imagination run wild and don't be held back by your AI solution.

We're a proud partner in our clients' success

The AI allowed us to create more interesting encounters in complex environments.

We would not have been able to make such an effective and robust co-op game without Kythera AI.

Early on in the game you may feel the AI in Aquanox isn’t very smart, but do not underestimate it! As you progress and improve your ship and skills, so does the AI.

It’s been liberating to work with a tested, high-quality middleware. We’ve been impressed by the design and debugging tools too, and look forward to iterating and expanding on our AI capabilities.

Norbert Varga

CEO | Digital Arrow

The transition to Kythera AI was seamless. They migrated our existing behaviors, minimizing disruption to our development team.

The excellent runtime performance means we can also have many more NPCs active. The result is we can fully populate our world and create a far richer experience for our players.

Great AI is crucial for us, and as a studio without dedicated AI engineers, Kythera AI is the perfect solution.

Their toolset easily integrates with our existing work in Unreal and lets us provide comprehensive, intelligent AI that we can maintain and continually improve.

I can't stress enough just how much Kythera AI has helped us on the journey.

By solving problems which would otherwise have taken infeasible amounts of developer resource, Kythera AI has opened up new creative possibilities.
