Key features
  • Coppola authoring tool for non-technical designers and writers to create dialogue and interactions
  • Pre-configured Archetypes with animation, behavior, dialogue and props ready to use
  • Deep Unreal Engine 5 integration with MetaHumans, Navmesh, and Behavior Trees support
  • Multi-agent and multi-modal planning for complex character interactions
  • Rehearsal text simulation to test dialogue before in-engine execution
  • Engine-agnostic C++ library with SDKs for Unreal, Unity and Roblox
  • Scale to hundreds of NPCs active simultaneously or thousands with streaming and LODs
  • 3.8× PhysX throughput on 20 benchmarks geometric mean
  • 13.0× performance on heterogeneous task mixtures
  • Per-environment work scheduling for efficiency
  • Reduced-coordinate articulation dynamics
  • Differentiable simulation
  • Rigid-deformable coupling support
