I am creating texture atlas (using FME 2022) from cityGML files at the time of tileset (cesiumjs) creation. But I am not able to find the texture atlas. I want to know where it gets stored?

The texture atlas will be included directly in the output binary b3dm files.

​

You'd need to decode the b3dm and extract them from the binary. Doable but not so easy

@virtualcitymatt​ , Thank you so much for your so helpful reply.

Please, can you elaborate a little, how to decode and extract texture-atlas from b3dm file? Just provide me some guidance.

Thank you so much once again

There are very few available options for reading b3dm - Probably the best option would be using this python library: https://oslandia.gitlab.io/py3dtiles/master/api.html#batched-3d-model
