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
