Draco compression for B3DM format tiles

Hi team,

I could compress OBJ file and generate drc file. But the requirement is to render the compressed B3DM files.

Have setup with help of this repo : https://github.com/google/draco

What extra config is needed for compressing B3DM ?

Referred to Sandcastle example of draco encoded mesh, it uses GLTF format.

Note : Cesium ion is not to be used in this case.

See my response here:

Let me know if that helps.
