The terrain layer export SOP exports a heightfield with the correct settings for Unreal. It does so by properly orienting the heightfield prior to export, and also remaps it into the expected range (0-256). This tool is designed to work together with Terrain Layer Import.
Save to Disk
This will export the heightfield to disk.
This allows you to specify if the tool is being used to export a heightfield from Houdini, or Houdini Engine. This is important to have correct in order to prevent rotated heightmaps. The tool should automatically detect what the host is, but its recommended to confirm manually.

The name used for the heightmap.
This is the folder on disk that the extracted maps will be exported to.

When Tile Method is set to Tile Size, this controls the resolution used for cutting up the heightfield into tiles.
Number of Tiles
When Tile Method is set to Number of Tiles, this controls the number of tiles the heightfield will be cut up into.
This controls the number of shared voxels that will overlap on the tile borders.
Determines the file naming used for each tile. Either based on UDIM, UV Tile, Frames or XY Tile.

Pad Tile Numbers
The padding used for tile numbers.
