LIVE-2 vs MESH TERRAIN

1. Mesh Terrain, introduced in UE 5.8, supports the RVT workflow:

https://dev.epicgames.com/community/learning/knowledge-base/nK7J/unreal-engine-introduction-to-mesh-terrain#creatervtassets
…so we can write classic heightmaps from mesh terrain into RVT assets

2. Ninja can sample RVT assets as height data source

Details:
(1) set up the Mesh Terrain segment (or any other mesh) to write into a on-disk RVT asset
(2) add RVT transformer to the Transformer Pipelines (previously, we had to use a material with “RVT Output” node included, to write RVT)
(3) create an RVT volume in the scene, connected to the same on-disk RVT asset the Landscape writes-to
(4) set ninja to sample the given RVT asset:
/LiveComponent /LiveInputFields /HeightFields /RVTHeightData /UseRVTAsHeightSource = True
/LiveComponent /LiveInputFields /HeightFields /RVTHeightData /RVT-asset = (user defined RVT asset)

Besides NinjaCore, External Renderers also support the RVT data pipeline:

• SurfaceAlignedVolumes
• SurfaceAlignedMeshes

Alternatively: we can go the top-down ScenaptureCamera data pipeline to capture height for ninja.
