Illuminating hidden objects shown in runtime

Is it possible? I don't (can't) use baking, I only use the realtime option, but when a user presses a button to reveal hidden geometry in a location, that geometry doesn't get lit by the interior lights, only the skybox, which makes it stand out and not very good looking.

Can this be fixed? I am using light probes (and reflection proves), but it doesn't seem to matter.

I'm also using static objects, currently, because I read that you are allowed to use ShowActive on them as long as you don't move them.

 

Apparently it is possible, but does someone know how?
