Accessing AssetsManager imports

Hi,

 

Im new to Babylon.js but it seems fun, I have a simple question about the code below. It imports models and places them in random positions, whats the most efficient way to re-randomise the positions every second? I tried with

 

setTimeout(function(){

window.location.reload(1);
}, 5000);

 

but this was a bit heavy, is there a way to just call the randomise bit again.

 

Also is this the most efficient way to load multiple models, the hardware I'm targeting is slow so anything I can do to get a bit more performance is best- maybe I should clone the objects?

 

Thanks
