[Therion] Wall visibility affecting lox model

[Footleg]

KML looks fine, as does the lox model.

I understand that the pit would look like a transparent hole if
rendered in a map without the lower scrap. Wasn't there are way you
suggested which might allow toggling the options on a line in
different maps Bruce? So you could have the pit filled in one map but
transparent in another?
