TerraForm generates a Landscape Actor from the DTM data you import into UE4. As well as providing a really slick way of creating accurate real-world terrains in UE4, this means that once you’ve imported your terrain, you can use all of the tools, content, physics and performance optimisations that Epic has built in, including:
- Landscape Sculpt tools – modify imported DTM (sculpt, smooth, flatten, ramp, add erosion).
- Landscape Paint tools – edit/modify Landscape Layer Masks.
- Landscape Blend Materials and procedural materials.
- Grasses and Foliage Spawners – procedurally add vegetation and clutter objects.
It also means you can use content available through the UE4 market place, including landscape materials, foliage and blueprints.
