Generic question HUGE model for world takes too long to load

[chicagobob123]

Generic question. I have a HUGE model for my world. Millions of polygons. 239MB babylon scene file. 

Generically HOW do you handle this? It takes minutes to load. 

For me I start zoomed out I need to see everything and as I zoom more detail. 

So generally how do you folks deal with this?

this is huge :0 just think about people with low bandwidth

Perhaps you could have multiple LOD? a simpler version and a more complex one

We support LODs in GLTF for instance

First think you should get a kick out of it loads on my Note 4 (not its intended target) and doesn't do too badly. 

On to your reply

>> I will have to look up LOD's cause I have no idea what that is. or GLTF for that matter 

I am working on multiple solutions. One of which is to just trash the entire model and try other ways to 

get the same visual effect.  I have so many basic questions. Sorry..

One of which is if I have a few common models with textures etc. that are reused.

Is there a way to keep them loaded in the gpu and re purposed with different attributes? 

Kind of like a texture tile being repeated all over the place. (does what I am asking make sense?  Maybe I have been up too long )

Trying to get some more performance. Is there a babylon how to get the performance paper ?

Textures are automatically reused when they are the same
