Labs Terrain Layer Export geometry node

The terrain layer export SOP exports a heightfield with the correct settings for Unreal.

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.
