    Is there any chance that scale unit for PBR Sky will be implemented, as it was implemented in original Bruneton scattering? I want to use atmoshpere in the space view for planets, where you can change the scale of the whole solar system. And there is no way to rescale atmosphere with the planet now. Changing planet radius, air height, etc will lead to recomputation and to incorrect results.

    This is the exact same issue I'm experiencing. The new PBS looks great at very large scales when viewing a planet from space, but awful when the planet is scaled down to allow placing objects near it. Trying to create a space cutscene is impossible with a large scale planet due to floating point warnings.

    Anyone from Unity able to comment on whether it's possible to scale the new physically based sky?

    Looking to source code, it is not currently possible. The question is could this be implemented in the foreseeable future.
