Sorry, I didn’t phrase carefully enough:

Yes this referred to external loaded resources only — as that’s what the city model blocks have, right?

But only ones that fit in memory at once, no? The new city model does not.

One of your guys did say that it’s not possible now but requires a small change — perhaps I misunderstood. In any case is simple and certainly solvable like all these points.

Thanks for the clarifications!
