Thanks to all.
It's a little bit terrifying to explore all possibilities Dan offered us.
Exploring the UCGO Cargos config, I see that.

That means that it's very easy to build a house with all it's own animations, lights etc... When spawning it via a UMmu.
But, it's a lot of work.
May be for the V3.0. :thumbup:
