Description

Convert navigation data into static meshes directly in-editor — no coding required.

Nav Mesh Exporter provides an easy way to convert a generated RecastNavMesh into a static mesh using a streamlined Blueprint-based Editor Utility Widget. With minimal setup, users can visualize or repurpose navigation meshes for use in level design, optimization, minimap generation, and more.

Whether you're a programmer refining navigation flow, or a designer looking to create invisible boundaries or debug pathing, Nav Mesh Exporter makes the process straightforward and accessible.

Features

  • Convert RecastNavMesh to Static Mesh with just two inputs.

  • Blueprint-based UI (Editor Utility Widget) — no C++ required.

  • Customizable and Extendable via Blueprints.

  • Dockable Interface for seamless editor integration.

  • Multi-purpose Output: use for visualization, gameplay logic, optimization, or rendering.

Example Use Cases

  • Level Visualization: Export your navmesh and bake it into a texture or render target for minimaps or UI overlays.

  • Navigation Cleanup: Filter out unnecessary navmesh islands and use the result to guide streamlined nav generation.

  • Invisible Boundaries: Generate walls or zones based on exported nav areas to shape player movement in a scene.

  • Debugging Tool: Visualize your navigation mesh as geometry to better understand AI pathing coverage.
