"You know... it might be not too difficult to add in a pre-rendered environment map that represented a basic 'in LEO orbit' scene. Possibly two; one for sun-lit, one for shadowed. Finally a small in-editor GUI would let you swap between the 'live' cubemap or the pre-rendered ones. (adding/using the pre-rendered cubemap would be dead simple. Getting a good pre-convolved one....much more difficult, but doable with the techniques that I currently know)
(if someone wants to open an issue ticket under TexturesUnlimited repo on the subject, it will ensure it doesn't get forgotten about)"
