Hello, cesium doesn’t support Hololens at present? I use version 1.12.2, which is currently packaged in Hololens without any images
Cesium for Unreal should support Hololens. Can you try applying a basic material like the default WorldGridMaterial to Cesium World Terrain and then packaging it? This will help us troubleshoot by figuring out if it’s a problem with the terrain data or the imagery.
