Terrain Importer for Unreal Engine (Python + Custom UE Plugin)
I built an end-to-end terrain importer that converts raw terrain dataset files into fully usable Unreal Engine landscapes automatically. Before this, importing and setting up ~45 landscape tiles in Unreal could take ~60 minutes and was easy to mess up. I wanted a fast, repeatable pipeline. It allows:
Python reads the dataset and generates Unreal-ready .r16 heightmaps
Python automation creates a new Unreal project and imports the heightmaps
Custom UE plugin (C++) builds Landscapes from the imported heightmaps and places them correctly in the level
Foliage: automatically placed across the terrain
The workflow reduce from ~60 minutes to ~5 minutes for ~45 landscapes (~12× faster) and made it deterministic and repeatable ideal when terrain needs frequent regeneration.
