使用CesiumIon的Clips裁切了一块地形和地图，为什么导入blender或者UE中发现范围远远超过裁切的范围？
Cesium Clips doesn’t ever cut individual triangles, it only discards entire triangles if they are outside the region. So one possible reason for what you’re seeing is that the terrain you’re clipping is quite low resolution, so there are only a few tiles covering the larger area that was exported. Can you tell us more about what tilesets you were clipping when you saw this?
步骤1：Clip imagery and terrain
步骤2：3954 Sentinel-2

步骤3：选择一块区域
步骤4：Format选择3DTiles
Ok, I tried this out, and I believe it’s working as intended. Because you’ve chosen to export 3D Tiles, the clip is exported at multiple levels of detail. The least detailed version looks like this:
Notice from the wireframe that it’s just two triangles. So there’s no way to reduce the spatial area covered by this model other than by clipping triangles, which Cesium Clips currently does not do.
The more detailed version of the model covers a much smaller spatial area, and is composed of more triangles:
Since you said you’re trying to get this model into Blender, I suggest telling Cesium Clips to export as glTF instead of 3D Tiles. That way you’ll get just one level of detail and it will cover a much smaller area.
谢谢你的答复
