Large number of .bin files in build

Cocos Creator
#1

I am using Cocos Creator 3 for my game.

When I build the project and run it;
I the network tab I see large number of bin files getting downloaded.

May I know what these files are?
Is there a way to bundle them to reduce the download time?

OR

Is there a build setting to adjust them?

Can anyone provide some help on this?

#2

Interesting. I can ask engineering.

#3

These files should be mesh files, from the uuid I think it’s a large model like Sponza with a lot of sub meshes, each bin file is a submesh

#4

@pandamicro I do have a model in the game with sub meshes.

Is there a way to reduce these separate file downloads?
