Big size model files

[Visam]

Hi

it is not a problem to load model files up to 200 MB. But if I need to load 500 MB, 1GB or even more, of course I have a problem: "google chrome ran out of memory while trying to display this web page".

I need to load whole model of a vessel or even oil platform. Any ideas? May be there is an "optimization" of babylon files? May be encreasing RAM help me?

but some time I can see another message for the same model in the "debug" window: "importMesh of undefined from undefined version"

Hello,

Keep in mind webgl has a limited context and memory... I'm not sure you can load a model of 500Mb all at once without doing any optimization.

You will have problem before hitting memory issues trying to load such big models. Indeed, it will fail most of the time at the network level. We had several issues in the past trying to do XHR requests higher than 100 MB and it's a browser limitation we can't override.

That's why we've been working on the incremental format also which helps you to move the problem later on.

Our Espilit demo: https://github.com/BabylonJS/Website/tree/master/Scenes/Espilit / http://www.babylonjs.com/demos/espilit uses incremental + binary format.

You should have a look to check if the incremental mode could help you: http://doc.babylonjs.com/tutorials/Using_the_Incremental_Loading_System

On a semi-related topic, how would one go about delaying javascript functions. I can't find anything like sleep and all the stuff I googled doesn't seem to delay the function at all. I was trying "async await" and even timeout wrappers but it doesn't seem to block anything. Or perhaps this is too off-topic.

I have a JS script populating a DB and was wanting to throttle it a bit.
