Exporting to OpenFlight

RoadRunner can export scenes to the OpenFlight (.flt) file format.

OpenFlight Export

From the menu, select File > Export > OpenFlight (.flt).

Export Options

Split by Segmentation

This parameter splits meshes by their segmentation type.

Tiling Options

The Export to Tiles parameter splits the meshes per tile. This parameter also groups props by the tile that they are in.

  • By default, only one file is exported. Tiles are stored in separate nodes.

  • If Export Individual Tiles is enabled, then each tile is stored in its own FLT file (for example, scene_Tile_1_2.flt).


  • Texture wrapping settings are not exported. This limitation might result in texture clamping issues for objects like signs.

  • The OpenFlight file is exported through the OpenSceneGraph plugin, which exports OpenFlight version 16.1.

  • RoadRunner does not export the normal or specular maps for materials.
