**Hi everyone**

**I generate a set of 3d-tiles model, and can display in cesium.**

**However, I can only pick each tile but not each individual building.**

**I have added batchid to gltf and convert it into glb and b3dm. But I still can not pick a building. (Which works in my previous project)**

**I’m using Cesium 1.38 and gltf 1.0**

**Here is my .b3dm file**

It looks like it’s missing the batch id attribute on the mesh.
