Export RAW Heightmap

This export writes the selected Polaris terrains into a RAW heightmap file. Use it when another terrain tool or pipeline expects height data as a .r8 or .r16 file instead of Polaris terrain data.

Access point

Open:

GameObject > 3D Object > Polaris > Terrain Wizard

Then go to:

Export Data > RAW Heightmap

How this export behaves

  • The source must be Polaris terrains in the scene.
  • Multiple Polaris terrains can be sampled together into one RAW file.
  • The final file layout depends on the chosen resolution, bit depth, byte order, and row order.
  • The exported file name is generated automatically based on the selected settings.

Main parameters

Source Polaris Terrains

The terrains to sample and combine for export.

  • You can gather all valid source terrains in the scene with Select All.
  • You can also add specific terrains manually or by drag and drop.

Output

Folder

The folder where the RAW file will be written.

Bit Depth

Controls exported height precision.

  • 16-bit is usually the safer choice for terrain exchange.
  • 8-bit is lower precision and more prone to visible stepping.

Byte Order

Used for 16-bit export so the file matches the destination application's expected format.

Row Order

Controls whether the output rows are written from bottom to top or top to bottom.

If the exported terrain appears flipped vertically in the destination tool, check this setting first.

Resolution

Columns and Rows

The output sample resolution.

  • Higher values preserve more shape detail.
  • Lower values reduce file size but lose detail.

Square

Pads the output to a square resolution using the larger of the two dimensions.

Auto

Computes a default resolution from the selected terrain grid.

Things worth noting

  • RAW export only captures terrain height.
  • The chosen bit depth, byte order, and row order must match the destination tool.
  • Resolution strongly affects fidelity. If the output looks softer or more stepped than expected, check the export resolution first.
  • When exporting multiple terrains together, the chosen resolution affects the whole combined result, not each tile independently.
