I would like to extract certain regions into Blender for editing. I was wondering if there is a way to export the 3D tiles using Unreal (or Cesium Ion) as OBJ along with textures (including OSM building data) or perhaps as embedded FBX format. Please let me know at your earliest convenience.
Currently, neither Cesium for Unreal or Cesium ion are designed to allow for exporting 3D tiles. I’d suggest visiting this issue for a little more information - How to load maps offline - #2 by RyanXRMG
Feel free to chime in on that issue with information about your use case! This will help us guide further development.
