HI ALLHow to add multiple layers and manage the relationship between them

Hi @dacong,

Currently only one raster is allowed to be draped over terrain. The feature to support multiple layers is on our roadmap Add support for multiple raster overlays on terrain · Issue #349 · CesiumGS/cesium-unreal · GitHub

Thanks Bao Tran for your reply and look forward to updating this function in the future
